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.
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.
