Car Traced In Murder Investigation
Police investigating the death of a man found lying injured on a pavement have traced a car seen near where he was discovered.
Albert McDonald, 58, was found with head injuries in Cumbernauld Road in the Riddrie area of Glasgow at about 9.25pm on Monday.
He was taken to Glasgow Royal Infirmary but died on the way to hospital.
Police, who are treating the death as murder, said his family are "completely devastated''.
Detectives earlier appealed for information about a car which was seen near where he was found. They said the occupant of the car has now been traced and will be assisting with their inquiries.
Senior investigating officer Detective Chief Inspector Laura McLuckie, of Police Scotland's major investigation teams, said: "We are following up several lines of inquiry, including speaking to local residents and accessing CCTV from around Cumbernauld Road and the surrounding area.
"Mr McDonald had significant injuries and we're trying to establish just how he sustained them by piecing together his last known movements.
"Understandably his family and friends are completely devastated, and specialist officers are providing them with support at this tragic time.
"It is imperative we find who is responsible for Albert's death. I would ask anyone who was in the vicinity of Cumbernauld Road around 9.30pm or earlier, and who may have seen anything suspicious to come forward to police.
"You may think that the information you have is insignificant, however it may be the piece of information we are looking for.''
She said she is confident that there will be more witnesses who could help as Cumbernauld Road is an exceptionally busy area at most hours of the day, being one of the main routes from the north and east of the city into Glasgow city centre.
