Man, 31, questioned over Londonderry knife killing
A 31-year-old man is still being questioned on suspicion of murder after a man was stabbed to death in Derry.
Christopher McGaughey, 56, was attacked at Hollymount Park in the Gobnascale area of the city at about 01:00 GMT on Sunday.
A woman suffered minor injuries in the attack.
It is understood the police are investigating whether the death was the result of some kind of domestic dispute.
Local priest Father Michael Canny said the dead man and his family were well-known.
"The community will be waking up this morning to this terrible, tragic and devastating news," he said.
"I think that all of our thoughts and prayers must be with the family and the extended family involved here."
