A murder investigation is under way after a man shot during a large-scale disturbance near a children's play area died in hospital.

The 23-year-old, named locally as Jamie Lee, was one of six people injured in the incident in Castlemilk, Glasgow, in which two men were shot.

He died from his injuries at Glasgow's Queen Elizabeth University Hospital on Sunday night. 

A 25-year-old man remains in serious condition in hospital while the other four men have been discharged.

Officers were called to the scene at Ballantay Terrace at around 8pm on Saturday following an incident involving two groups of men, whom police now believe were attached to two local gangs embroiled in a feud. 

Police said the six men sustained injuries consistent with a variety of weapons being used.

One woman told the Daily Record: “Some kind of vendetta has been going on for a long time now.

“The bad blood is between two families."

“I don’t know what it is about and I don’t want to know."

Detective Chief Inspector Martin Fergus of Police Scotland's Major Investigation Team said: "It is vital that we trace everyone involved in this incident."

He added: "We will have extra patrols in the area for the foreseeable future and we would encourage the public to come forward and speak to these officers with any information they have or indeed any concerns they have."

The other attacks are being treated as attempted murder and serious assaults.

Earlier Mr Fergus told the BBC: "We're working on the hypothesis this may well just be a localised feud amongst families, we don't know at this stage, this is what we're attempting to piece together."

He said that two men "received injuries consistent with gunshot wounds".

Police do not believe the incident is linked to any others in the Glasgow area over the last few months or any ongoing police investigations, and said there is nothing to suggest the incident was racially motivated.

Anyone with information is asked to contact officers at Helen Street Police Station on telephone number 101 quoting incident number 3874 of July 8.

Alternatively they can call Crimestoppers anonymously on 0800 555111.

A report will be sent to the procurator fiscal.

A team of about 10 forensics officers were seen at the rear of a nearby property.

Each of them was combing a grass area on their hands and knees while CID officers knocked doors beyond the police cordon.

One member of the public in his 40s, who asked not to be named, said: "They were all pals those involved, but just had a disagreement and it escalated.

"It's tragic what happened."
