A man who was fatally stabbed in an apparently unprovoked attack in Glasgow city centre has been named by police.
Michael Davis, 21, from the Germiston area, was stabbed in West Campbell Street as he walked to work at about 1935 BST on Wednesday.
He was taken to the Royal Infirmary where he later died. Police are treating his death as murder.
His attacker is described as of Chinese appearance, 6ft 1in tall, of slim build with short black hair.
He was wearing a dark beanie-style hat, waist-length zipped jacket and black woollen gloves.
Sup Nelson Telfer, of Strathclyde Police, said: "Enquiries are at an early stage to establish the exact circumstances surrounding this horrific and totally unprovoked attack.
"We know the man was going between jobs in Bothwell Street and Bath Street. The area would have been particularly busy at this time of night with people leaving work and heading home or people heading out for a meal or drink.
"The area is extensively covered with CCTV and officers are currently studying the footage and carrying out enquiries with local residents and businesses.
"I would appeal to anyone who was in the area of Bothwell Street around the time of the attack and may have witnessed the incident take place, or anyone with any information relative to the investigation, to come forward as a matter of urgency."
