Images of four people present at the Hillsborough disaster have been released by Operation Resolve as part of its ongoing appeal to identify potential witnesses who officers wish to speak to on behalf of the coroner.

Six new images, part of a collection of more than 100 pictures, have been distributed to the public in order to aid the identification of individuals who helped victims on April 15 1989.

Previous appeals have resulted in 41 identifications thus far, with 59 people yet to be traced.

The public are asked to visit to view the full gallery of pictures and they can also call 08000 283284 if they are able to identify an image
