A man has been seriously injured after being hit by a car as he was crossing a busy High Wycombe town centre road. 

The man in his fifties was crossing the A40 Oxford Road at the traffic lights near the Chiltern Taps pub at around 6.30pm on Friday when he was hit. 

The car, which fled the scene, is believed to be a blue or green 4x4. 

The seriously injured pedestrian was left unconscious in the road after being hit. 

Police say the impact of the crash was "significant" - meaning the driver would have realised they had hit something. 

Investigating officer PC Tom Smith, of the Joint Operations Unit for Roads Policing, based at Amersham police station, said: "It is likely that the driver would have been aware they had hit something or someone.

“The vehicle is believed to be a 4x4 type vehicle, possibly blue or green.

"I would like to appeal to the driver of the vehicle involved to contact police as soon as possible.

"I am also keen to speak to anyone who witnessed this collision or saw the vehicle driving away.”
