POLICE say there is nothing to indicate that a a mass brawl and shooting in Glasgow, now the subject of a murder investigation, was related to a gangland feud.

Detective Superintendent Allan Burton, of Police Scotland, said that the incident had been the result of a rift between two groups, apparently known to each other, who arranged to meet for the battle to take place.

However a Major Investigation Team set up to look into the fatal disturbance had yet to establish a motive for the encounter, he said.

His comments came after police named the man who was shot in the incident in Castlemilk on Saturday night as Jamie Lee, 22. He lives in the area and has a partner. Police said it was not known if they had any children.

Mr Lee was one of six people injured. It was reported that his father, named locally as Joseph, was among those treated in hospital for injuries after the incident.

About a dozen individuals were involved in the brawl close to a children’s playground and the police are calling for witnesses to come forward.

DS Burton said: “We know from CCTV that there were other people in the vicinity, including children who ran off when the incident started. We have not identified who those children are, or who their parents are, or whether they saw anything.

“There are other people shown on the CCTV looking out from their home addresses or in the vicinity who will have crucial information. They may be waiting on us coming to them, would prefer they come forward and would urge them to do so.”

He said forensics officers were trying to establish the nature of the firearm used to fatally injure Jamie Lee, as well as a 62-year-old man who was treated in hospital and later released. Mr Lee died with a gunshot wound on Sunday evening at Queen Elizabeth University Hospital in the city. His death is being treated as a murder. Five other men injured in the disturbance were treated for injuries, but have been discharged. Police said the other attacks are being treated as attempted murder and serious assaults.

As well as the firearm, others in the two groups had been armed with weapons, including bladed and ‘baton-style’ weapons, DS Burton added. He said: “This is clearly a worrying incident for local residents and families who live nearby, but I want to assure people that this level of violence in our communities will not be tolerated and we will be using every available resource to arrest those responsible for these violent attacks.

“We have had an encouraging response from the local community so far but I know that there are still people in the area who have not spoken to us. I would urge them to get in touch.”

Police remained at the scene on Monday and a team of about10 forensics officers were seen at the rear of a nearby property, examining a grass area on their hands and knees while CID officers knocked doors beyond the police cordon.

Officers do not believe the incident is linked to any others in the Glasgow area over the last few months or any ongoing police investigations.
