A man has been hit in the face with a "heavy object" before having his car stolen.

Police are now appealing for witnesses following the robbery in Gravesend on Sunday (October 21).

Officers were called at about 5.45pm to Valley Drive after a blue Lexus IS200 was reported to have been stolen.

The owner of the vehicle had stopped at the traffic lights when he was approached by two men.

It’s alleged the driver was struck in the face with what has been reported as a heavy object before the two men made off in the car.

The victim was taken to Darent Valley Hospital where he was treated for facial injuries.

Later that evening, at about 7.15pm, the stolen Lexus was seen by an unmarked police patrol on the High Street in Northfleet.

In an attempt to get away, the driver of the stolen vehicle began reversing at speed before colliding with a grey Nissan Pixo and then the police vehicle.

The driver of the Pixo and her passenger suffered whiplash injuries and were taken to Darent Valley Hospital.

The suspects managed to get away on foot and police have now released descriptions of the two men.

The first man has been described as white, believed to be about 25-years-old, of medium build with short black hair, and was wearing a dark blue jacket.

The second man was white, also about 25-years-old, of medium build with brown cropped hair and was wearing a white shirt.
