THE SEARCH: Forensic officers gather evidence in Springburn.
Emergency services were called to the Springburn area, in the north of the city, at 11.30pm on Monday night following reports a man had been assaulted.
The man, named locally as Ryan Sherry, was taken to Glasgow Royal Infirmary where he later died.
The attack happened in Petershill Road, near the fire station, and is said to have followed a disturbance involving other people.
It is thought the man, who was from the Springburn area, may have been chased from a nearby close in Petershill Road before the attack.
Strathclyde Police said they were following a positive line of inquiry but have urged witnesses to come forward.
A post-mortem examination was being carried out to establish the exact circumstances of the death.
The detective leading the inquiry said the death had left a Glasgow family starting the new year "in extremely sad circumstances".
The area was sealed off by police in the early hours of the morning. Officers were carrying out door-to-door inquiries in the area yesterday and gathering CCTV images to assist them with their investigation.
Strathclyde Police officers are keen to speak to an elderly couple who were walking their dog in the area at the time and have appealed to them to come forward.
Detective Superintendent Kenny Dewar, from London Road CID, said: "A young man has lost his life and one family is beginning this new year in extremely sad circumstances.
"I am appealing to local residents who may have seen or heard anything in connection with this incident, in parti- cular the elderly man and woman who were out walking their dog.
"They may have seen something or have information which could assist our inquiry and I am asking them to please get in touch with us."
Friends of the dead man spoke of their shock and posted tributes on Twitter.
One said: "Just can't get my head around the fact someone who I remember as being so lovely has had his life taken so young. RIP Ryan Sherry xx"
Another said: "Such sad news to wake up to today, absolutely gutted. RIP Ryan Sherry, amazing guy will be missed."
