More than 1,600 people have come forward as witnesses to the Hillsborough disaster in Sheffield, as new inquiries continue into what happened and why.
The Independent Police Complaints Commission is looking into the actions of police officers in the wake of the 1989 disaster, which claimed 96 lives, after it emerged that police officer statements were altered in a bid to shift blame.
Another investigation, known as Operation Resolve, is looking at what caused the disaster and whether there was any criminality.
Information uncovered is being passed to the coroner overseeing new inquests into the deaths.
A new witness appeal led to 1,634 people coming forward.
Rachel Cerfontyne, Deputy Chairman of the IPCC, said: “Our research indicates 275 of the respondents appear not to have given an account previously.
“We will be prioritising contact with these people to obtain more detail about their experience.
“More than 900 people have already received communication from us. But we acknowledge there is a significant number still to be contacted.
“The ongoing analysis work of all the responses will allow us to categorise and prioritise the respondents and we aim to have advised all respondents what is happening with their account as soon as possible.
“Our witness appeal remains live.”
