The vile film posted by an Instagram account “cranhill_fleeto” was edited with a disturbing “happy hardcore” soundtrack.

It shows the victim lying on the floor with an attacker jumping on his head.

The youngster is now being treated in hospital for injuries, thought to be serious. Reports online claim he was in a coma in hospital after the attack.

British Transport Police (BTP) confirmed he was taken to hospital but have refused to give more details.

BTP also refused to say if the train attack, filmed on board a service between Glasgow Queen Street and Bellgrove stations, at 11.47am last Friday, is connected to Justin’s murder at 3.45pm the next day.

The force previously appealed for witnesses for that attack, in the city’s east end, which was carried out by youths wearing face coverings and balaclavas.

They did confirm there had been three arrests after the attack.

A spokesman said: “Three teenage boys were arrested in connection. They have since been charged and will appear at court on December 14. The boys arrested are 13, 15 and 16.”

One source said: “The video doing the rounds was posted by somebody saying they are a member of Cranhill Fleeto, which is a notorious gang. It shows at least two assailants chasing one victim and then getting him on the ground, where one jumps on his head.

“There is daylight within the carriage and ordinary people sitting, getting on with their journeys. It is sickening to watch and utterly disgusting that anyone would make such a video in the first place then publish it online.”

The Cranhill Fleeto is a street gang from the east end of Glasgow. Sources have told the Record that a teenager named in captions posted on the video is notorious for involvement in gang violence.

One commentator claimed the victim of the train attack on Friday was one of Justin’s friends.

A subsequent altercation is claimed to have happened after a group, including Justin, came face to face with a rival gang before Justin was fatally stabbed.

A fund has been set up to help Justin’s family with funeral costs.

He was taken to the Queen Elizabeth University Hospital after the attack at High Street station in Glasgow on Saturday. He was pronounced dead a short time later.

Detective chief inspector Brian Geddes, of Police Scotland’s major investigation team and the senior investigating officer, has appealed for witnesses.

Detective Inspector Marc Francey described Justin’s murder as a “shocking act of violence in broad daylight”.

John Mason, MSP for Glasgow Shettleston, added: “It’s tragic for somebody of that age to lose their life with their whole life ahead of them.”
