Thames Valley Police is issuing a CCTV picture of a vehicle as its occupants may have information about an assault in Aston Clinton last week.
At around 11.20am on Wednesday (2/11) on the A41, London Road, Aston Clinton just outside Aston Clinton Park, the victim, a man in his sixties, stopped in his car at temporary traffic lights moments after a minor traffic incident had taken place further up the road.
A man approached the victim's vehicle while he waited at the lights. They had a verbal altercation and then he punched the victim ten times in the face causing cuts and heavy bruising.
The victim had to attend Stoke Mandeville Hospital for treatment.
