Daniel’s blue Skoda Octavia was rammed off the road near Junction 16 of the M8 in the city’s Port Dundas area after he was pursued by two stolen cars.
The vehicles, a silver VW Golf and a black Audi S3, forced the Skoda off the road and Daniel, who runs a private hire cab firm, was assaulted and stabbed repeatedly in the face.
Police and an ambulance crew who attended the scene initially believed he had been blasted with a shotgun due to the extent of his facial wounds.
It has been reported Daniel – whose mother, Annette is a jailed professional shoplifter – lost an eye in the attack.
But this has been denied by relatives and close associates of his late uncle, heroin dealer Jamie Daniel, the head of the organised crime family who died last July from cancer.
One associate said: “Bonzo was told to get out of Glasgow. He was warned things were getting too hot and that he was on a death list.
“He knew the risks but chose to get a Kevlar vest and brazen it out. That went well for him, didn’t it?
“He is in a bad way and could have been killed. His face is terrible, but no one in the family knows anything about him losing an eye.
“There is damage. A lot of damage. He has a very sore face.”
Detectives discovered the VW and Audi dumped and torched at different locations within hours of the attack, which is being treated as attempted murder.
They believed the stabbing is linked to a string of shootings in and around Glasgow related to a feud between the Daniel crime family and rivals from a number of gangs.
The attack is also being linked to the shooting of two men outside schools, the execution of a drug dealer, a failed murder bid on a senior Daniel family member and the mowing down of a taxi and loan firm boss who lost both legs.
Detective Chief Inspector John Kennedy said the attack was “targeted” and appealed for anyone with information to come forward.
