The burnt-out car was found in Granby Lane

The burnt-out silver Mercedes was found in Granby Lane in the city's west end and is undergoing forensic tests.

Kriss was abducted in Pollokshields on Monday by a gang of Asian men and his mutilated body was found the next day.

Police believe the car was set alight at 2015 GMT on Monday and are seeking two males seen running from scene.

One witness told investigating officers they saw an Asian and a white man run away from the vehicle while it was ablaze.

It is also believed the car may have been stolen from Lanarkshire last month with officers hoping to prove this via the tests.

Another car, thought to have been used in the crime, has also been recovered and is in the hands of the forensic team.

Detective Superintendent Elliot McKenzie said that at this stage he was unable to confirm if either vehicle was the one involved.

Kriss Donald was a 15-year-old schoolboy

However, police believe the discoveries may be a major breakthrough in tracking down Kriss's killers.

The results of both examinations are likely to be completed on Friday.

Earlier on Thursday, Kriss's mother Angela Donald urged people not to target the Asian community because of his death.

Mrs Donald, who has four other children, blamed gangs for the death of her eldest son.

She said: "Five men, full of hate, and it doesn't matter to my family and extended family what colour these men are, murdered my eldest son."

Race relations

Earlier in the day Superintendent Kenny Scott said he could appreciate the concerns of the public but he believed the incident was an isolated one.

But some residents in the south side where Kriss lived and was abducted, believe his murder could have been racially motivated.

Police have tried to reassure the community, insisting that racial tensions were "very low" in the area.

Flowers and other tributes have been left at the abduction scene

Margaret McDermid, 62, a friend of the Donald family, said racial problems in the area have been "going on for years and years".

She said: "There have always been arguments between white boys and coloured boys."

Another woman, who declined to be named, said many people were afraid to go down Albert Drive, a busy street with many Asian shops nearby, for fear of fights between gangs of youths.

Kriss was walking on Kenmure Street with a 19-year-old friend when the attack happened.

While the friend managed to escape, Kriss was bundled into a silver car thought to be a Mercedes or a BMW.

Community mourning

At the local grocers, Gulmarg Superstore, the shopkeeper said the Asian community was also saddened by the teenager's death.

Umar Hyat, 19, said there were tensions in the area.

"This is very wrong and very sad," he said. "We need more police and security in this area."

Sixty officers, including 40 detectives, have been assigned to the investigation.

Police stressed that they were continuing to establish a motive for the murder.

Flowers, Glasgow Rangers shirts and teddy bears have been left at the corner of Kenmure Street and McCulloch Street alongside messages from friends and family.
