Bristol protest witness appeal as IOPC investigates man’s death

The Independent Office for Police Conduct (IOPC) is appealing for witnesses after a man died shortly after police contact at a counter-protest in Bristol earlier this year.

Nicholas Stone, aged 65, suffered a cardiac arrest after attending the event in Bristol city centre on 10 January.

CCTV shows Mr Stone falling to the floor after interacting with two police officers in Clare Street just before midday. He got up and spoke to the officers before walking away. He left the counter-protest, arranged in response to a protest organised by the Bristol Patriots, at around 1.20pm, but died a short time later.

We have launched an independent investigation into the contact Avon and Somerset Police had with Mr Stone and we are appealing for anyone present who may have seen Mr Stone’s interaction with the police to come forward.

IOPC Director of Engagement, Derrick Campbell, said: “Our sincere condolences go to Mr Stone’s family and friends and everyone affected by his death.

“There were many people at the protest on 10 January and it’s possible that a number of bystanders may have witnessed what took place between Mr Stone and the two police officers on Clare Street.

“It’s important we establish the circumstances surrounding this incident so we urge anyone who may have witnessed or filmed the incident or the moments leading up to it to come forward and tell us what they saw.”     

After the reassessment of a mandatory referral made by Avon and Somerset Police in January 2026, we decided an independent investigation was necessary, which began in May 2026.

We have met with Mr Stone’s family to explain more about the scope of our investigation and how it will progress and we will ensure they are kept updated throughout.
