It happened at about 6pm on Wednesday and the pair then pulled up at the traffic lights at Wolvercote Roundabout.

The BMW driver, apparently in a road rage-fuelled fury, got out of his car and started shouting at the 54-year-old man driving the Mazda.

Police said he 'punched the victim in the face multiple times' and inflicted a 'laceration' to his face, and he had to have stitches at the John Radcliffe Hospital. 

Investigating officer PC Matthew Stansfield, based at Cowley station, said: "This was a vicious and unprovoked attack that took place on a busy road in heavy traffic.

"I am keen for any witnesses to come forward with information, particularly any individuals who captured this assault on their dash-cam."

The attacker is described as a white man, around 5ft 9ins tall, with dark hair. He was wearing a hooded top and tracksuit bottoms.

His victim has since been released from hospital.

Anyone with information can make a report on the force's website or call 101, quoting reference number 43200042315.
