Investigators are searching for several more people, including one thought to be from Nottingham, to help with the Hillsborough inquests.
More Images have been released involving potential witnesses helping victims on the pitch during the 1989 FA Cup semi-final between Liverpool and Nottingham Forest.
There is no image available for one of them, but she is known to be an off-duty nurse who helped victims in the back of an ambulance, pictured above.
Operation Resolve is a new investigation into the Hillsborough disaster, ordered by Theresa May, to uncover whether any organisation or individual is legally culpable for the disaster.
A new inquest examining all of the deaths in detail is also ongoing.
The disaster left 96 Liverpool fans dead and fuelled the Taylor report, which led to the modernisation of all major stadia in the UK.
So far, investigators have released images of more than 100 potential witnesses they would like to speak to.
Around 24 people have been traced so far.
Last week officers released CCTV images as part of the appeal for the first time, showing groups of people carrying victims out of the stadium.
A full gallery showing all of the current appeals can be seen on the Operation Resolve website.
Anyone with any information is asked to contact detectives on 08000 28324.
