A man has been arrested for questioning following the murder of another man outside Belfast early yesterday.
The 22-year-old victim was named locally last night as Ciarán Irvine. He was stabbed in an incident in the Juniper Park area of Dunmurry on the fringes of west Belfast following a nearby house party.
He was found with a stab injury to his back and was taken to hospital where he died a short time later.
Police have called for witnesses to come forward, believing that many people in the area at the time must have information. Forensic experts carried out an examination of an address at a block of flats and cordoned off the scene where the murder took place.
Public representatives were quick to condemn this latest knife killing.
SDLP Lagan Valley Assembly member Patricia Lewsley said: "This killing has sent shock waves across the whole of Belfast, what type of people can kill a young man with such brutality and force?
"The killer or killers must be found. I appeal to people to come forward with any information, no matter how small, to help police with this investigation."
Michael Ferguson, a Sinn Féin councillor in west Belfast, said residents were "shocked and horrified".
"I have spoken to the young man's family and they are traumatised by what has happened. Here was a young man who went out of an evening and ends up dead."
