Detectives investigating the murder of a man found dead in an alleyway have made two arrests.
The victim was discovered off Creggan Street in Londonderry in the early hours of Sunday.
Police said he had sustained “significant” head and body injuries.
A 35-year-old woman and 51-year-old man were arrested later on Sunday on suspicion of murder.
Detectives from the Police Service of Northern Ireland’s major investigation team are conducting the murder probe.
“The man has sustained significant injuries to his head and body and a post-mortem examination is due to take place to determine the cause of death.”
Mr Corrigan urged anyone with information to come forward.
The area around Creggan Street and the Little Diamond were cordoned off on Sunday as forensic officers examined the crime scene.
