A video has emerged of a brawl between a cyclist and several occupants of a car.
The footage, shot by a member of the public in the middle of the road in Slough, shows a cyclist approaching a car, having left his bicycle by the side of the road.
He leans into the car and begins punching the driver.
The driver, another man and a passer-by begin to fight in the street, and one of the car occupants wields a walking stick at the cyclist.
The footage was shot in Bath Road, Slough, at about 12:30pm on Thursday, and sent to the BBC by an anonymous contributor. It is not clear what prompted the fight.
Thames Valley Police, which has been shown the video by the BBC, said the incident was not being investigated as it had not been reported.
