A further 11 witnesses to the Hillsborough disaster who helped dying Liverpool fans are being urged to come forward.
Nine new CCTV images have been released in an attempt to track down the witnesses, who it is believed will be able to assist the ongoing inquests into the deaths of 96 Liverpool supporters at the Sheffield Wednesday ground in 1989.
It is the fourth appeal of recent weeks that has been made on behalf of the coroner Sir John Goldring.
Of the 59 people sought so far, 28 have either come forward themselves or been identified by people who knew them.
The fresh inquests began in March 2014 and are expected to be hearing evidence into next year.
The inquests have recently moved into a new phase, in which the circumstances involving each individual death is being examined.
Evidence is setting out the narrative of the day for each of the victims from when they arrived at the FA Cup semi-final, how they got in, which terrace pen they went into, their experience in the pens and what happened following the crush that led to their deaths.
Assistant Commissioner Jon Stoddart, who is running Operation Resolve, which is assisting the coroner’s work, said of the witness appeal last month: “There are still many questions that the families of the 96 have and we believe that these people may be able to provide answers to some of those questions.”
Anyone who can identify any of the people in the images is asked to call Operation Resolve on 08000 283 284 or via the website www.operationresolve.co.uk.
