Police are hunting a man who shouted racist abuse at a taxi driver before climbing out of the cab window, spitting and kicking at the vehicle.
The Met have released CCTV footage of the man after the cab driver was racially abused in Chelsea earlier this year.
The incident occurred in Kings Road in the early hours of Sunday March 22.
The man is described as white, approximately 6ft tall, and was wearing a white shirt and a charcoal grey suit.
The victim, a licensed black cab driver, had picked up a man in Camberwell New Road, SE17, at approximately 1.15am.
A short while later the man started to shout at the driver; the driver eventually stopped the cab in Kings Road, Chelsea, at around 1.30am and asked the man to pay his fare and leave.
The man refused and shouted further abuse, some of a racial nature, police said. He then climbed out of the window of the cab, spat and kicked the vehicle before making off.
The victim reported the incident to police at 7.50pm that day and an investigation was launched.
CCTV from inside the cab filmed the incident and the image of the man has been circulated to officers but he has yet to be identified.
Anyone with information is asked to contact Kensington & Chelsea police via 101 or call Crimestoppers anonymously on 0800 555 111.
