Images of two witnesses have been re-released in an attempt to find people who helped dying fans at the Hillsborough Disaster.
Officials from Operation Resolve are trying to trace a number of people who were at the game on the day of the 1989 disaster when 96 Liverpool supporters died.
The latest appeal follows detailed enquiries by investigators after people were identified when the pictures were first released.
Detectives have spoken to the two people who were initially believed to be the individuals pictured.
It is hoped those involved will come forward and may be able to assist with the new inquests in Warrington.
So far, images of 129 people who were at the ground on the day have been released, with 62 identified.
