text: A student remains under police guard in hospital after being kidnapped, tortured with pliers and forced to drink bleach by masked men in an apparent revenge attack for 'accidentally scraping a man's car'. Motaz Zaid, who is currently studying economics at the University of Greenwich, was with a friend in St Marks Close in Parsons Green, south west London, in the early hours of Friday when the group of thugs targeted them. His friend, who wishes to remain anonymous, said the pair were sprayed with ammonia and assaulted with tools before Mr Zaid, 20, was bundled into a Mercedes C220 Estate and driven off. Motaz Zaid was with a friend in  Parsons Green, south west London, in the early hours of Friday when the group of thugs targeted them. Mr Zaid was apparently bundled into a Mercedes by masked men and attacked . The friend, 19, who was stabbed several times in the back and legs during the ordeal, was left for dead in the quiet residential street while Mr Zaid was found dumped a few miles away, close to the A3 on the border of New Malden and Parsons Green. Police became alerted to the incident after spotting the vehicle in Beverley Way, Kingston, at about 1am. Uniformed officers approached the stationary car, but it drove off and fled from the scene despite attempts by police to pursue it. Officers then discovered Mr Zaid dumped on the side of the road with life-threatening injuries. He was taken to a south London hospital, which cannot be named for security reasons, where he remains in a critical condition. His friend was also taken to hospital with stab wounds but was later discharged. The friend recalled the incident today and told the Evening Standard: 'They had been parked waiting for him to get back. As we both got out of the car, these five guys just jumped us. They sprayed something in our eyes and it blocked our vision. 'They weren't after me, they were beating him up. I tried to fight them off and to grab him but he was on the floor and not moving. I hit one of them in the face and three of them chased me into the main road and stabbed me. 'By the time I got back to my friend the car had left and I thought he had got away but after looking for him I realised they had taken him in the car.' Mr Zaid, 20, who is currently studying economics at the University of Greenwich, was found dumped at the side of the A3 in Beverley Way, Kingston, south west London (above). He remains in hospital with critical injuries . Mr Zaid's father Azz said his son's injuries were 'very serious', adding: 'My heart is broken when I see my son like that. I can't believe anyone could do that to another human being.' He said he believes the incident is in response to a minor altercation last week. He said his son was allegedly involved in an accident with another car, in which one of the vehicles became slightly damaged. He claims the other driver refused to negotiate a settlement and threatened violence if his son did not pay £400. Metropolitan Police said officers from the Trident Gang Crime Command are currently investigating the incident and trying to trace the suspects . Officers confirmed the car involved was a Mercedes C220 Estate but said it is not known how many suspects were in the vehicle. Scotland Yard confirmed no arrests have yet been made in connection with the incident. Anyone with information should contact police on 101 or Crimestoppers anonymously on 0800 555 111.
