A teenage thug has been convicted of murdering a 14-year-old boy at a railway station.

Daniel Haig, 18, stabbed Justin McLaughlin in the heart during a broad daylight attack on October 16 2021.

Jurors heard how the dying schoolboy - who had celebrated his birthday two days earlier - begged for his mum as friends came to his aid on the platform of Glasgow's High Street station.

Justin was rushed to the hospital but never survived the single blow delivered by Haig, who was 16 at the time.

Haig denied murder but had admitted stabbing the boy.

He claimed he had only wanted to "injure" Justin after a fight at the station shortly before the attack.

Haig was convicted following a trial at the High Court in Glasgow on Thursday.

He now faces a life sentence when he returns to the dock.

Justin and his friends had gone into Glasgow that afternoon for food at a McDonald's.

They then returned to High Street station where Haig and a friend were already.

The trial heard a remark was shouted towards the pair about the area in Glasgow they were from.

Haig then said to his friend: "All of them are running at us."

Haig told jurors he got a knife from his rucksack and hid it in his waistband.

His friend pleaded with him "not to do anything stupid".

But, the court heard Haig instead ran at the group and a fight broke out on the platform.

After the scuffle ended, Haig jumped onto the track to retrieve the blade which he had dropped.

CCTV captured him chasing the youngsters again - Justin tripped and fell before Haig caught up and plunged the knife in him.

The thug grabbed his rucksack, raced up the station steps and onto the street leaving behind his wounded victim. He tossed the bloodied knife in a bin.

A friend of Justin recalled the boy staggering towards a flower bed at the station.

In pre-recorded evidence, the 14-year-old girl stated: "He said something like: 'They have got me'. He fell face first onto the ground.

"Justin was trying to stand up. He kept saying: 'I need my mum...I need to go home'."

"His lips had turned blue and white. The other boys (with them) were crying."

Justin's phone then rang as he lay stricken at the station.

The witness said: "It was like his mum or something. One of the boys answered. I do not know what he said."

Justin was rushed to the city's Royal Hospital for Children, but never recovered. He had been stabbed in the heart.

Haig gave evidence and told his KC John Scullion that he had not set out to kill anyone that day.

He claimed to have had the blade for "protection" having been attacked a day earlier.

Haig feared Justin - who he had never met before - and the others had followed him to the station.

He planned to use the weapon to "chase" them away, but admitted then stabbing Justin although only to cause a "minor injury".

Mr Scullion put to him: "How do you feel that you killed Justin McLaughlin? His family are in the courtroom."

Haig: "I feel really bad about it. I would like to apologise to them. It was never my intention to kill anyone."

Prosecutor Steven Borthwick KC later put to Haig that after the fight stopped on the platform, he was under "no threat".

Mr Borthwick said Haig instead got his knife from the tracks and chased the group.

The advocate depute: "You were intending on doing serious damage to one of them."

Haig said: "No."

Mr Borthwick said: "You have seen the video - it looks very much exactly what you were intending to do."

Haig replied: "No."

The teenager then refuted the suggestion he was a "liar".

It emerged after the verdict Haig attacked a man with a garden fork - and was later caught with blade - months before the murder.

On July 31 2021, Callum McDonald had been at the Clachan Bar pub in Glasgow's Baillieston.

He then left to go to a local bookmakers as Haig loitered nearby with a group of other youths.

Prosecutor Mr Borthwick said: "He became involved in an altercation with Haig and was assaulted with a garden fork or similar item.

"He suffered cuts and bleeding, but declined medical treatment."

Two days later - just yards from the high court where he was eventually convicted of murder - he was clocked on CCTV with a blade.

Mr Borthwick said he was searched at Glasgow Green and a blue lock back knife was found.

Haig had pleaded guilty to these charges prior to the trial, but it could not be reported until the end.

Regards the murder, Lord Clark told the young thug: "This was a dreadful act of stabbing with a large bladed knife that went straight through his heart."

Justin's family had sat through the trial listening to often harrowing evidence.

After the verdict, they paid tribute to their "blue eyed boy" with a "smile that lit up the room".

The family said: "Justin had his full life ahead of him. Our life will never be the same.

"He was the character of the family - his younger brothers miss him so much.

"He was their best friend as well as a brother. It is a family devastated by knife crime."

Haig was remanded in custody and will be sentenced in August.
