But last night the black victim ruled out a racial motive for the attack, claiming it was prompted by other factors in the relationship, police said.
Mark Glasgow, 30, from Charlton, south-east London, is recovering in hospital with serious burns and severe bruising to his leg and jaw. He was attacked at about 8.30am on Thursday, soon after making a short visit to his girlfriend's home.
Police say he was stopped by a man dressed in black and brandishing a gun, who forced him into the back of a vehicle. He was beaten up and knocked unconscious before being driven to Lullingstone Park golf course, near Swanley, Kent. He was then beaten up again, doused in petrol and his groin set on fire. It is thought there may have been two attackers, both of them white.
Mr Glasgow was taken to Queen Elizabeth Military Hospital, Woolwich, south-east London. A spokesman described his condition yesterday as 'comfortable'.Reuse content
