A gang of carjackers who dragged former boxer Michael Watson 500 yards (450m) along a road in a failed attempt to steal a car have been convicted.
The 51-year-old, who was left partly disabled after a fight with Chris Eubank in 1991, was attacked along with his carer in Chingford last year.
Simon Luck, 29, Paul Samuels, 31, and Anselm Legemah, 23, also sprayed ammonia in the eyes of their victims.
They were found guilty at Snaresbrook Crown Court of two separate attacks.
On 16 February, the gang sprayed ammonia in the face and eyes of Watson's carer Lennard Ballack then beat and kicked him as they tried to steal a car.
As the men drove off Watson became trapped by his seatbelt and was pulled along the road.
The gang then abandoned their attempt, leaving a bottle of ammonia on the front passenger seat.
