A man was reportedly assaulted while he was sat in traffic in his car on a motorway slip-road.

At around 11.30am on Saturday, March 4, the driver was travelling towards the Dartford Tunnel on the M25 when he left the motorway at Swanley.

Investigating officer, PC Lexi Carter, said: "Other motorists were in the queue at the traffic lights and may have witnessed this incident.

"An investigation is underway and we are appealing to anyone who may be able to assist our enquiries to contact our appeal line."
