Kriss Donald's partially-clothed body was found on the Clyde Walkway

Jamie Wallace had been describing how he and his 15-year-old friend were attacked by Asian men as they walked in the Pollokshields area of Glasgow.

The 22-year-old had to pause four times as he told the High Court in Edinburgh about the events of 16 March 2004.

The three accused have denied racially-motivated murder.

The trial heard the attack came as Mr Wallace and Kriss walked down Kenmure Street.

In court he identified one of the accused, Imran Shahid, as the man who had attacked first, and called him "Baldy".

However, the trial also heard that in October last year Mr Wallace failed to pick out Mr Shahid in an identity parade.

The best thing to do, in view of the length of time he has been in the witness box, is to stop his evidence today and resume it tomorrow Judge Lord Uist

Defence QC David Burns, for Mr Shahid, asked why Mr Wallace had not named "Baldy" as one of the attackers when he first spoke to police.

Mr Wallace agreed that at the time he did not know Baldy, and had not met him.

But he had "a reputation" he added.

The witness was also questioned about his drinking, his use of cannabis and prescribed medication and his mental state at the time of the incident, until the judge called a halt.

Lord Uist said: "You heard this witness in the course of his evidence asking for a break on several occasions and he asked for another break.

"I decided the best thing to do in the circumstances, in view of the length of time he has been in the witness box is to stop his evidence today and resume it tomorrow."

Before the halt, Mr Wallace said a Mercedes car had arrived in Kenmure Street during the fight.

I was trying to fight back and trying to watch myself - I was trying to distract them Jamie Wallace

He said: "Two doors opened and they were trying to drag him (Kriss) into the car."

Mr Wallace said the attackers tried to punch him as well as his friend.

"I was trying to fight back and trying to watch myself. I was trying to distract them," he said.

He described how Kriss had tried to use his hands and feet to stop himself being dragged into the car, but his jacket was pulled over his head and he was bundled in.

"I seen them putting his head in first, then the two doors shut and they were sitting on him and punching him on the back," he said.

The trial has heard that his partially-clothed and scarred body was found the following day on the Clyde Walkway.

Mr Wallace said the Mercedes drove away and he crossed the street and told a woman who was pushing a pram.

Special defence

He then phoned a friend with the same news, went to his grandmother's house, then to a nearby shop to phone the police, the court heard.

Mr Burns suggested that at the time of the alleged abduction, Mr Wallace was drinking heavily, smoking cannabis and taking medication for paranoia.

Mr Wallace said: "That is the medication I was prescribed but I wasn't taking them."

Asked to describe his "paranoia", he said: "I get anxiety attacks and panic attacks."

Imran Shahid, 29, his brother Zeeshan Shahid, 29, and Mohammed Mushtaq, 27, have been accused of abducting Kriss, repeatedly slashing him with knives or similar instruments and setting him on fire after a drive to Dundee and back.

The charge against them alleges they were acting with two other men - Daanish Zahid, who is serving life for the murder, and Zahid Mohammed, 22 - who served half of a five-year sentence for assaulting Kriss and lying to police.

Imran Shahid has lodged a special defence blaming Daanish Zahid and Zahid Mohammed "and others" for the murder.
