A 64-year-old man had to be taken to hospital after being punched in the head on a busy dual carriageway – prompting police to urge drivers with dashcam footage of the attack to come forward.

The incident happened last Sunday (October 22) at around 7.30pm on the A404 between Marlow and Handy Cross, approximately 200 metres before the Handy Cross roundabout.

The victim was driving his car in lane two along the A404 from Marlow towards J4 of the M40. He was undertaken in lane one by the offender who was driving a white Ford Fiesta, that is believed to be registered in around 2012.

The attacker pulled into the second lane and forced the victim to stop his car in the middle of the busy road.

Both drivers got out of their cars, and following a confrontation, the victim returned to his car. The attacker then walked up to the victim, who was sat in the driver's seat, and punched him three times in the head, before driving off.

The victim sustained swelling and bruising to his cheek, and a bloody nose. Police said he required hospital treatment but has since been discharged.

The attacker is described as a white man, aged between 20 and 30-years-old, approximately 5ft 10ins tall, slim with dark short curly hair and clean shaven.

He spoke with a local accent. At the time of the incident he was wearing a white jumper underneath a long length woolly coat.

Police confirmed no arrests have yet been made.

Investigating officer PC Leigh Andrews, based at High Wycombe police station, said: “I would like to speak to anyone who witnessed this offence or anyone with dashcam footage of the incident.

“We believe there to be a number of witnesses as the two vehicles were blocking lane two of the A404, which caused traffic delays.”

Anyone with information or dashcam footage of the incident can contact police on 101 quoting reference 43170317737, or Crimestoppers anonymously on 0800 555 111.
