Metropolitan Police have released CCTV footage of an attack on a forecourt which left a man with a fractured jaw.
The incident occurred after two men were seen parking a car in the forecourt of the Esso petrol station in Broadway, Bexleyheath, south-east London on Wednesday 5 October.
But a dispute was sparked when the 36-year-old victim asked the men to move the car.
The CCTV footage shows the victim talking to the one of the men but the assailant then punches him, before fleeing the scene.
The suspect has been described by the Metropolitan Police as being a white man in his early 30s with a beard and short brown hair.
He was also wearing black shorts and dark t-shirt with a white square logo.
Anyone with information is urged to call police on 101 or contact Crimestoppers anonymously on 0800 555111.
