A violent thief punched a driver in the face before ordering him out of his car and driving off in it.

Police are appealing for information after the victim, a 20-year-old man from Dartford, was stopped in his blue Vauxhall Astra at the traffic lights between Lowfield Street and Princes Road at just after midnight on May 18.

A man opened the driver's side door and punched his victim in the face before telling him to get out of the car.

When he did so the suspect drove off in the car, which was discovered burnt out in Belvedere later the same day.

The offender is described as white, around 5ft 10ins and aged around 20 to 30 years old.

He had short, scruffy hair and a mole or a birthmark on his cheek under his left eye.

He wore a grey top and blue jeans.

DC Christopher Mason said: "I'm keen to hear from anyone who has heard about this incident or anyone who might have been on the same road at the same time and noticed a disturbance."
