A TEENAGE thug killed a stranger just 30 minutes after he had been freed by police for slashing a shopkeeper.

The 15-year-old punched Patrick Colquhoun, 70, who fell and suffered a fatal injury following the attack on Victoria Road in Glasgow's Govanhill on April 12 this year.

The boy had that same day struck Nadeen Mohammed with a blade after an incident at the 65-year-old's off-sales.

The teenager - who cannot be identified due to his age - today appeared in the dock at the High Court in Glasgow.

He pleaded guilty - via his KC John Scullion - to the culpable homicide of Mr Colquhoun.

The boy also admitted to assaulting Mr Mohammed to his injury.

He will be sentenced next month. The 15-year-old is currently detained at a secure unit.

Prosecutor Angela Gray KC told how there had been "concerns" raised about the boy's behaviour in 2023.

The attack on Mr Mohammed occurred after the boy and a friend had gone to the store in Govanhill around 4pm on April 12.

They demanded the shopkeeper and his son "come outside".

Instead, the men told them to leave. Mr Mohammed then followed them before there was an altercation.

Miss Gray said: "The boy removed a knife from the waistband of his trousers and made a slashing motion towards Mr Mohammed striking him on the arm."

The man ended up needing stitches for a wound.

The teenager fled, went home and told his father what happened.

The dad then drove back to the scene and admitted to police there his son "had been involved in an incident".

It lead to the boy being arrested that night.

Miss Gray said: "At 11.15pm, he was released from police custody having given an undertaking to attend at Glasgow Sheriff Court on April 30, 2024."

The boy was picked up by his mother but jumped out of her car after becoming angry with her.

Around the same time, Mr Colquhoun had left his local bar the Queen's Park Cafe to visit a nearby takeaway.

The ex-taxi driver was described as being in "good spirits" and had never caused any bother.

At 11.42pm - after collecting his food - Mr Colquhoun was seen standing behind a car rented by the boy's dad.

CCTV then captured the teenager coming into the street and accusing the OAP of urinating at the motor.

Miss Gray said: "A witness saw the boy go towards Mr Colquhoun and punch him on the head."

The court heard the victim fell backwards after being attacked and struck his head on the road as he hit the ground.

The young thug then walked off as members of the public rushed to help the victim.

At one stage, the boy's father is seen on CCTV moving the car away as a person does chest compressions on a stricken Mr Colquhoun.

The court heard mercy crews who arrived could not save the pensioner.

He had suffered a brain bleed, a large skull fracture and bruising.

The fact Mr Colquhoun had been drinking that night may have triggered a brain condition which could have been a "a potential contributing factor" in the death.

The teenage attacker was traced via CCTV and was spotted hiding in a doorway.

He was again arrested and stated: "I slapped him. He was p***ing on my father's car.

"I shouted at him, but he would not listen."

Mr Colquhoun - who lived in the city's Pollokshields - is survived by his sister Margaret Salasidis and brother Tony Colquhoun.

Lord Harrower deferred sentencing for a background report until October 18 in Edinburgh.

He ordered the boy to remain in the secure unit where he is currently held.
