Man Attacked In Paisley
A man has suffered potentially permanent scarring and physical impairment after being attacked by two men while sitting in his car.
The ''vicious'' attack happened at about 3.45pm on Friday in the old Co-operative car park in Bridge Street, Linwood, Paisley.
The 29-year-old victim had been sitting in his silver Skoda Octavia when two men got out of a white Vauxhall Corsa and attacked him, police said.
He sustained serious cuts to his hands and arms and was taken by ambulance to the Royal Alexandra Hospital in Paisley. Medical staff describe his condition as stable.
The first suspect is described as white, in his twenties, is 6ft tall with a broad build and wearing dark clothing and a waist length waterproof jacket.
The second suspect is described as white, in his twenties and wearing dark clothing, a short waist length jacket and a black and orange hat.
Detective Sergeant Ally Semple said: ''The motive for the attack is still to be established. It was vicious and I have no doubt that the two suspects were determined to inflict serious injury to the man and cause significant damage to his car. It is entirely possible that he will be permanently scarred and could have long-term impairment to his hands and arm as a result of the attack.
''This all took place in the middle of the afternoon in an area where members of the public, including young children, were about. Very frightening for anyone to witness let alone experience.
''The white Corsa, which we believe was fairly new; about two years old and had black alloy wheels, was driven at speed in to the car park and made off again, also at speed, so someone may have noticed it as a result.
''Anyone with information that will help officers with their inquiries is asked to contact the CID at Paisley Police Office via 101 or Crimestoppers on 0800 555 111 where details can be given in confidence.''
Detectives say she was subjected to the common assault on Wednesday.
