Police are speaking to man about the death of a 62-year-old whose body was discovered in a Glendalough unit.
Officers were called to a Cayley Street unit at about 7.30pm yesterday and discovered the body of a man who lived at the address.
It is understood the man lived alone and may have died several days earlier.
Shocked neighbours said they heard an argument at the property on Sunday but did not think anything of it until police arrived last night.
A man is assisting detectives with their investigation.
Police have not revealed how the victim died.
