Detectives investigating the murder of 21-year-old east Belfast man Reece Leeman have confirmed he was stabbed following an altercation at a property on Kyle Street.
Mr Leeman was found collapsed on Connsbrook Drive after being seriously assaulted on Friday morning.
Detective Inspector Joanne Harris said: “My thoughts today are very much with Reece's family and friends who are trying to come to terms with their sudden loss.
"We received a report at 1:50am on Friday that a male - which we now know was Reece - had been stabbed and subsequently collapsed on Connsbrook Drive.
"Police and the Northern Ireland Ambulance Service attended and Reece was taken to hospital where he tragically died from his injuries."
A 28-year-old man has been arrested on suspicion of murder and he remains in custody assisting police with enquiries. Police have been granted an additional 36 hours to question the 28-year-old.
An 18-year-old man, who had been arrested on suspicion of murder, was released unconditionally. The teenager was then re-arrested on suspicion of aggravated burglary and robbery. He has been released pending a report to the Public Prosecution.
DI Harris said: "Our investigations continue today and I am following a number of lines of enquiry.
"At this time, however, I can say we are not seeking anyone else in relation to Reece's death but I do want to make a number of specific appeals in a bid to piece together Reece's movements in the final hours before his untimely death.
"I know Reece had gone to an address on Kyle Street with another male sometime before 1:50am. Some type of altercation occurred inside the house when Reece was there. He was subsequently discovered collapsed on the street on Connsbrook Drive with stab wounds.
"I want to appeal to anyone who was in the area at the time. Did you witness the assault on Connsbrook Drive? Did you see Reece leave the house in Kyle Street?
"I also want to ask anyone who saw Reece, or who spoke with him the day before, or during the early hours of the Friday morning to get in touch with us. I would also ask anyone who saw Reece with another male during these times, if they know his movements prior to Reece's death, to contact us.
