The murder victim whose body was discovered in a main street in Belfast has been named.
He was Mohsin Bhatti, aged 29, and had lived in India Street, close to where he was found dead at around 5am on Thursday.
Meanwhile, police also offered more details about the suspect they had arrested over the killing.
On Thursday, the PSNI had said he was believed to have been of African descent, and on Friday confirmed that he was from the east African nation of Somalia. He is aged 32.
He had sustained minor injuries, and on Friday police said he was transferred from police custody to a secure medical facilty.
He is being detained there under the Mental Health Order.
Detective Chief Inspector Richard Campbell said the dead man’s relatives had been informed of his killing.
He reiterated his earlier call for information, saying: “I want to hear from anyone who saw or spoke with Mohsin during Wednesday or in the early hours of Thursday morning before he was stabbed.”
Police said it was believed some kind of altercation may have taken place in a flat at India Street, which then spilled out on to Botanic Avenue where he died.
Throughout Thursday the normally-lively street – in the heart of the city’s student and pub district – was silent and deserted as police erected a large cordon around it.
It re-opened around 6.30pm.
Anyone with information which may assist detectives is asked to call a special incident room at Musgrave PSNI station by dialling 101.
