Tragic Co Derry man Conall Kerrigan who was found dead last month, may have been the victim of a robbery, police have said.
Police have released photographs of two men who they say may have information.
Detective Inspector Conor McStravick said: “Conall Kerrigan died on Sunday 23 August. He had been at the Metro Bar earlier, but left there, and was later seen on the city walls. He was last seen on the walls near Foyle Street at around 3.03am on Sunday morning.
“At this stage we do not believe that Conall’s death was as a result of a crime, however, we believe that his wallet was stolen from him sometime before his death.
“No wallet was found in his possession when his body was discovered, but after extensive searches, it was recovered by police.”
The detective added: “I would like to speak to the two men pictured who may have information about the robbery or the movements of Conall Kerrigan in the early hours of Sunday 23 August. The men, or anyone who knows them, are asked to contact detectives at Strand Road Police Station on the non emergency number 101.”
