POLICE have issued a photograph of a man they wish to speak to in relation to the death of Claudy man Conall Kerrigan in Derry last month.
It's believed the 25-year-old who was a member of John Mitchel GAC in Claudy, died after falling from the city's walls in the early hours of Sunday August 23.
It is believed he had been in the Metro Bar on Saturday evening and left at around 2am. Mr Kerrigan's body was discovered at around 10.20pm by friends and family searching for him.
Police revisited the scene yesterday morning and are hoping to trace any witnesses who may have seen Mr Kerrigan on the walls and can help officers find out exactly what happened in the minutes leading up to his death.
Police have said they don't believe Mr Kerrigan's death was as a result of a crime but his wallet had been stolen from him as he sat on the walls.
Detective Inspector Conor McStravick, who is leading the inquiry, said: "The purpose of this revisit was to see if we could make contact with anyone who may have been on the walls four weeks ago at about the time Conall was there.
"He had been in a local public house, and we believe he was on the walls and in Foyle Street for some time afterwards.
"A check of CCTV footage has produced an image of Conall on the walls at 3am. We believe he died subsequent to that sighting."
Mr McStravick said several people saw and spoke to Conall around that time and has issued a grainy photograph of someone who, it is believed, may have seen or spoken to him.
"I would stress that he is regarded purely as a potential witness," he said.
"This witness is believed to have left the area in a white taxi car which collected him and people with him in Foyle Street close to Sandino's bar.
"If that man sees this photograph, or if you know or recognise him, please contact the detectives at Strand Road station on the 101 non-emergency number.
"We do not believe that Conall’s death was the result of a crime, however, we are keen to establish as far is possible all of the circumstances on behalf of both the family and the coroner."
