Police are looking to trace the driver of a sports car that failed to stop following a crash on the A11.

The incident happened on the northbound carriageway close to the A1307 Fourwentways junction, at Babraham, at about 10.30am on Saturday (December 14).

It resulted in a black Vauxhall Zafira losing control and crashing into the central reservation. A mother and two young children were in the vehicle and were not hurt but were badly shaken.

The other vehicle involved was a red Porsche 911 and officers want to speak to its driver.

Anyone with information should contact PC Stuart Hilton, at the roads policing unit, on 101.
