Police are appealing for witnesses after a woman was assaulted in a road rage attack at a Thetford Forest concert.

A silver estate car and a Mitsubishi L200 collided in the car park as gig-goers left following a performance by The Script at High Lodge on Thursday night.

The estate driver, a man in his 50s, got out and opened the Mitsubishi driver's door.

He grabbed the woman's arm but drove off when a passenger intervened, leaving the victim with bruises.

The assault happened at about 10.40pm and the estate car had a registration plate JRO.

A total of 8,250 people attended the open-air gig - the biggest ever attendance for a gig on Forestry Commission land in Britain.

Witnesses are asked to call the crime investigation bureau on 01473 613500 or Crimestoppers anonymously on 0800 555111.
