A man is being treated for stab wounds after he was attacked by a group who smashed the window of the van he was sitting in.
The 30-year-old was in the passenger seat of a grey Vauxhall Combo van in Torrance, near Bishopbriggs in East Dunbartonshire, when a car stopped in front of the vehicle, blocking it in.
A group of men armed with knives got out of the Audi, smashed the passenger window of the van and assaulted the victim in what police said was a targeted attack.
The driver of the van, a 34-year-old man, drove off and stopped at the Asda on Kirkintilloch Road, Bishopbriggs, where an ambulance was called.
The victim was taken to Glasgow Royal Infirmary for treatment to several stab wounds.
Medical staff describe his condition as serious but stable.
