• Read more about New evidence

1. Both investigations gathered a wealth of new evidence. As well as taking witness statements from thousands of those who had been at the match—including police officers, supporters, media, SWFC staff and volunteers—the investigations recovered documents that were assumed to have been lost or destroyed. This included more than 8,000 pocket notebooks belonging to SYP officers and the policy books of the officer that led the WMP investigation, providing a major insight into the way WMP conducted its work. In addition, video material from the day was obtained from various sources, and recordings of radio messages and communications between the PCB and the Force Control Room (made using a system manufactured by Racal) were secured and examined.
    
2. Both investigations also: 
    
   • used witness appeals to attempt to reach people who had not previously given their account
   • conducted searches of key locations that resulted in new evidence being found
   • applied to the courts to gain access to video material that had not previously been provided
   • made use of the evidence of expert witnesses in specific topics. Some of these were appointed by the investigations—for example, a health and safety inspector from the Health & Safety Executive (HSE) was seconded to work as part of the Operation Resolve team—while others were instructed as expert witnesses to the Goldring Inquests
      
3. Despite this comprehensive approach, there remain some gaps in the information related to the disaster. 
    
   • Some potentially significant documents have not been found, such as minutes of debriefs of previous matches at Hillsborough Stadium; others have been damaged and are no longer fully legible.
   • Some material has, wholly legitimately, been destroyed or disposed of over time.
   • Some witnesses, who may have been able to provide additional insight, could not be interviewed. In part, this is because the investigations began more than 23 years after the disaster; some witnesses had died, while others were in poor health.
   • This length of time also meant that many individuals could not recall all matters accurately or in detail.
   • A small number of potential witnesses declined to engage with the investigations, as is their right; some of these explained that they had already given one or more accounts and had nothing further to add.
      
4. Nonetheless, the two investigations had access to more material about the disaster and its aftermath than any previous investigation or inquiry. 

The vast quantity of new material gathered by the investigations has been assessed and, where appropriate and where the original owners give their consent, will be transferred to The National Archives for long-term preservation. 

• Read more about The evidence examined

1. The Hillsborough investigations gathered and reviewed a vast quantity of evidence. The IOPC and Operation Resolve re-examined the documents disclosed to the HIP, having brought them back together in a single location from archives around the UK. The investigation teams also obtained, and restored, the HOLMES databases (specialist IT systems used to support large police investigations) used by the previous investigations into the disaster. In addition, the teams reviewed 2,700 individual pieces of AV material from broadcasters, CCTV and audio recording systems, as well as approximately 23,000 still images.
    
2. The material disclosed to the HIP included minutes and notes from a large number of meetings involving police officers and other parties. These included meetings after the disaster between SYP officers and its appointed legal team. While these would have been conducted under legal professional privilege, because the meeting minutes were disclosed to the HIP, the documents entered the public domain and could be used as evidence.

• Read more about The Goldring Inquests

1. In 2012, following the publication of the HIP Report, the then Attorney General applied to the High Court to have the Popper Inquests’ verdicts, of accidental death, quashed. The application was successful, and the Goldring Inquests began in 2013.
    
2. The IOPC and Operation Resolve conducted enquiries for the Goldring Inquests and provided more than one million pages of investigative material, such as witness statements and documents, together with hundreds of hours of AV material. Operation Resolve also produced a comprehensive timeline of the movements of each of those who died, built from AV material and witness statements, and its senior investigating officer presented detailed background evidence about the disaster.
    
3. The Goldring Inquests hearings ran for 308 days, spread over two years, and heard evidence from more than 1,000 individuals. Having heard the evidence, the jury concluded that all of those who died in the Hillsborough disaster were unlawfully killed—a profound and momentous change from the conclusion of the original inquests.
    
4. As part of its conclusions, the jury was also asked to answer a series of questions. One of these was, “Was there any behaviour on the part of football supporters which caused or contributed to the dangerous situation at the Leppings Lane turnstiles?” The jury responded “no”. They were then asked if there was any such behaviour which may have caused or contributed to the dangerous situation; again, the answer was “no”.

• Read more about Criminal trials that resulted from the investigations

1. As a result of their investigations, both the IOPC and Operation Resolve referred a number of individuals to the Crown Prosecution Service (CPS) for it to decide whether anyone should face criminal charges in relation to the disaster or its aftermath. In June 2017, six individuals were charged with criminal offences. 
    
   • Ch Supt Duckenfield was the SYP match commander on the day: in other words, he was the officer in charge of the police operation. He was charged with manslaughter by gross negligence. He went on trial in January 2019, and the jury was unable to reach a unanimous or a majority verdict. He then faced a retrial in October 2019, at which the jury found him not guilty.
   • Mr Mackrell was the SWFC Secretary and designated safety officer at the time of the disaster. He was charged with two offences under the SSGA 1975 and one offence under the HSWA 1974 relating to the turnstile arrangements. He went on trial at the same time as Ch Supt Duckenfield. He was found guilty of the offence under the HSWA 1974 and fined £6,500.
   • Norman Bettison, a former chief inspector and superintendent with SYP and subsequently Chief Constable of Merseyside and of West Yorkshire. He was charged with four offences of misconduct in public office in relation to the allegation that he lied about his involvement in the aftermath of the Hillsborough disaster and about the culpability of Liverpool supporters. This prosecution was discontinued by the CPS on 22 August 2018, following a review of the evidence. This is examined further in chapter 20.
   • SYP officers Ch Supt Denton and DCI Foster were charged with perverting the course of justice for their involvement in amending fellow SYP officers’ accounts before they were submitted to the Taylor Inquiry. Peter Metcalf, a solicitor from a firm called Hammond Suddards, which was acting for SYP in 1989–1990, was also charged with the same offence, for his role in the amendment process, including suggesting specific changes to officers’ accounts.
      
2. These latter three went on trial in April 2021. On 26 May 2021, the judge ruled that the defendants had no case to answer. This was because the offence they were charged with was perverting the course of justice in relation to the amendment of officer accounts presented to the Taylor Inquiry. As the Taylor Inquiry was a non-statutory departmental inquiry, it was not a course of justice, so the case required the prosecution to demonstrate that the amendment of these accounts was also intended to affect the Popper Inquests or the subsequent criminal investigation conducted by WMP—both of which were courses of public justice. The judge concluded that the prosecution had failed to demonstrate this.
    
3. This report includes more details of the evidence provided by Operation Resolve and the IOPC that led to these charges and the trials that followed.

• Read more about Status of the investigations

1. The two investigations were both criminal investigations, meaning they could result in people facing criminal charges—and both did. They were also police disciplinary investigations, which examined whether police officers acted in line with the professional standards of the time (see Appendix B), in planning for the event, on the day of the disaster and in its aftermath.
    
2. The two investigations responded to 260 complaints about the actions of the police in relation to the disaster. These ranged from complaints that SYP officers at the stadium failed to respond effectively to the situation that led to the disaster, to complaints about the way WMP officers interviewed supporters in the weeks that followed. Some complaints were discontinued after initial investigative steps were taken. In addition, the investigations identified 92 conduct matters for investigation, some of which involved multiple officers. These were matters where police officers may have committed a criminal offence or behaved in a manner which would justify disciplinary proceedings, but there had not been a complaint about the matter.
    
3. Some of the complaints investigated were first made in 1989. Material cited in the HIP Report raised questions about whether these had been investigated properly, in line with the requirements at the time. The IOPC wanted to reopen these complaints, but legislation did not allow it to reinvestigate matters which had been previously investigated under the oversight of the Police Complaints Authority (PCA), the national body that oversaw complaints against police officers in 1989. The IOPC sought an amendment to the Police Reform Act 2002 (PRA) to make reinvestigation possible. The Police (Complaints and Conduct) Act 2012 added a new section, 28A, to the PRA, giving the IOPC discretionary power in exceptional circumstances to reopen complaints that had been investigated by the PCA.
    
4. Each complaint and conduct matter has been investigated in its own right and an individual report has been produced, as part of the statutory process for making decisions relating to alleged misconduct by police officers. (See Appendix C for more details of this process and the role of the IOPC in it.) Complainants and the officers under investigation have been informed of the outcomes, as have those identified as interested persons in any of the individual investigations.
    
5. In total, the IOPC upheld or found an officer would have had a case to answer (so would have been expected to face disciplinary proceedings) in respect of 92 complaints in relation to police actions before and during the disaster, and in its aftermath. Similarly, it found that in 18 conduct matters, officers would have had a case to answer. In total, the IOPC found that 12 officers would have had a case to answer for gross misconduct, if they had still been serving. That means that if a disciplinary panel agreed, they could have faced dismissal. In a further four complaints, the IOPC found that officers would have had a case for gross misconduct, but it was not possible to identify who the officers involved were.
    
6. From the outset, it was understood that no officer would face disciplinary proceedings as a result of the IOPC and Operation Resolve investigations, even if it was found they had a case to answer. This was because they were subject to the legislation in force when the investigations commenced; at that time, officers who were no longer serving with a police force could not be subject to disciplinary proceedings.
    
7. Similarly, complaints had to be assessed against the police professional standards at the time of the disaster. These were very different to the standards in place today.
    
8. The IOPC can only uphold complaints or find a case to answer for misconduct where the available evidence meets the legal thresholds it must apply.
    
   • To be able to uphold a complaint, the IOPC must conclude that, on the balance of probabilities, the force or officer did not deliver the service to a standard that was expected of them.
   • To give an opinion that there would be a case to answer for a complaint or conduct matter, the IOPC must be of the opinion that there is sufficient evidence upon which a reasonable misconduct panel could conclude there has been a breach of the professional standards that amounts to misconduct.
      
9. Reflecting this, the IOPC could not uphold complaints where there was insufficient, contradictory or missing supporting evidence, or where the complaint was made about a decision taken elsewhere. For example, complaints about individual WMP officers using questionnaires to gather information from witnesses could not be upheld, because the decision to gather information in this way was made by others.
    
10. The fact that a complaint is not upheld does not challenge the account of the complainant.

• Read more about What has been investigated?

1. The Operation Resolve investigation examined the planning for the 1989 Semi-Final, the events of the day leading up to the disaster, the emergency response and aspects of the immediate aftermath of the disaster—notably the way that the families and friends of those who died were treated by the police and other authorities. In investigating these issues, Operation Resolve looked at the roles and responsibilities of organisations that were involved in staging the match, including (listed alphabetically): 
    
   • Eastwood & Partners, the engineering firm that advised the stadium owners, SWFC, on ground structure and layout
   • the FA, which selected Hillsborough Stadium as the venue for the match
   • SCC, the local authority that, under the Safety at Sports Grounds Act 1975 (SSGA 1975), was responsible for overseeing the safety of professional sports grounds in Sheffield
   • SWFC, which owned Hillsborough Stadium
   • SYCFS, which assisted in the emergency response to the disaster
   • SYMAS, which also took part in the emergency response to the disaster
   • SYP, the force responsible for policing on the day
      
2. Operation Resolve also investigated the actions of individuals who worked for these organisations and whether any of them may have committed criminal offences.
    
3. The IOPC investigation focused on key aspects of the aftermath of the disaster—in particular, the allegations that police officers may have deliberately altered or suppressed evidence about the disaster and may have sought to deflect blame away from the police by focusing on the alleged behaviour of some of the Liverpool supporters. 
    
4. The IOPC examined the actions of SYP officers in preserving, gathering and presenting evidence to the various investigations that followed the disaster, including the Taylor Inquiry and the Popper Inquests. It also examined the work of WMP, the force appointed in the days after the disaster to support these investigations and inquiries and to gather evidence for them.

The full terms of reference for both investigations are included at Appendix A.

• Read more about The decision to start two new investigations

1. The HIP Report, and the questions it raised, led to a decision to open new inquests into the disaster and separate decisions to start two new investigations.
   
   
   • The investigation into the disaster itself was given the name Operation Resolve. Operation Resolve was a police-led investigation, set up specifically to examine the events leading up to and including the disaster. It was launched in December 2012 at the direction of the then Home Secretary, Theresa May MP, and a dedicated team was recruited to undertake it. To ensure independent oversight and scrutiny, the elements of the Operation Resolve investigation relating to the police were managed by the IOPC.
   • The investigation into the actions of police officers and police forces in the aftermath of the disaster was started in October 2012 by the Independent Police Complaints Commission (IPCC). It was subsequently taken forward by the IOPC, the organisation that oversees the police complaints system in England and Wales. The IOPC was established in January 2018 as a successor to the IPCC. It investigates the most serious matters involving the police, including deaths following police contact, and sets the standards by which the police should handle complaints.

• Read more about Previous investigations

1. The Taylor Inquiry was promptly set up to investigate the causes of the disaster and to seek to prevent similar events occurring. It was followed by inquests and a criminal investigation. 
    
2. However, the families of those who died in the disaster, survivors and other campaigners have long maintained that these previous investigations were unsatisfactory and that the truth about what happened that day had not yet emerged. Their campaign led to several appeals, reviews and other judicial processes, including a private prosecution, in which one of the officers on trial for manslaughter and misconduct in public office (Supt Murray) was acquitted and the jury was unable to reach a verdict on the same charges against Ch Supt Duckenfield.
    
3. The campaign continued and in 2010 led to the formation of the Hillsborough Independent Panel (HIP), to oversee maximum possible public disclosure of information related to the disaster. In 2012, the HIP published a report to explain how the information that had been disclosed through its work added to public understanding of the tragedy and its aftermath. The HIP Report identified material that had not been considered by previous investigations and inquiries into the disaster. This material raised new questions about how people died, whether the disaster could have been prevented and how the police acted in the aftermath of the disaster. 

• Read more about The Hillsborough disaster

1. The Hillsborough disaster refers to events at the FA Cup Semi-Final football match between Liverpool and Nottingham Forest at Hillsborough Stadium on 15 April 1989. A devastating crush developed on the West Terrace at the Leppings Lane end of the stadium, which resulted in the deaths of 97 Liverpool supporters. In addition, hundreds were injured and many more left traumatised by the events.
   
   
2. SYP was responsible for the police operation at the Semi-Final. The actions of the force, and its officers, in relation to the disaster have been examined in several previous investigations.

• Read more about 1. Introduction

1. This report provides an overview of the evidence gathered by two linked investigations into the Hillsborough disaster and its aftermath:
    
   • a police-led investigation, known as Operation Resolve, into the disaster itself
   • an investigation by the IOPC into police conduct in the aftermath of the disaster
      
2. The report aims to add to public understanding of the disaster and its aftermath, specifically in relation to the actions of the police forces involved. By setting out the evidence gathered, it aims to help answer allegations of potential police misconduct.
