Witness Appeal In Glasgow Murder
Detectives investigating the murder of a man have appealed for four potential witnesses to come forward.
Stephen Gannon, 36, was attacked by two men at Broomfield Lane in the Springburn area of Glasgow at about 5.10pm on Friday.
Emergency services were called but Mr Gannon, who lived locally, died at the scene. Police said the two attackers ran off in the direction of Balgrayhill Road.
They want to speak to two men carrying Asda shopping bags who were seen walking in adjacent St Monance Street around the time of the incident.
An appeal has also gone out to the occupants of a white transit van which drew up nearby before the passenger alighted and entered a block of flats.
Detective Chief Inspector Allan Burton, from Police Scotland's major investigation team, said: "I am making a direct appeal to these four people - they were in the area at the time of Mr Gannon's attack and we believe that they will have information which could assist our investigation and ultimately lead to the arrest of the two men responsible for Mr Gannon's death.
"We are continuing to carry out door-to-door enquiries and officers are still reviewing CCTV images from the surrounding area in an effort to find out further information regarding the suspects and the incident.''
