Police are asking for witnesses and dash cam footage following a collision on the M25 involving a silver Hyundai Ioniq driving against the flow of traffic.

The incident started on 27th January at around 1.20pm when the vehicle was reported to police in Potters Bar and failed to stop.

Following a pursuit through Potters Bar, the Hyundai entered the M25 at junction 24 heading towards junction 23, travelling in the wrong direction.

Due to the risks posed to other drivers, the pursuit was discontinued, but the vehicle was later stopped on the motorway by a marked police car driving in the correct direction.

A 43-year-old man was arrested on suspicion of failing to stop, dangerous driving, theft of a motor vehicle, driving under the influence of drugs, and going equipped. He remains in custody for questioning.

The collision also affected a white Audi, a black Jaguar, a roadside assistance vehicle, and a minibus.

The Audi's driver, a man in his 60s, was taken to hospital as a precaution by paramedics from the East of England Ambulance Service.

Sergeant Tim Davies of the Bedfordshire, Cambridgeshire, and Hertfordshire Road Policing Unit is asking witnesses to assist with enquiries.

“I am appealing for independent witness accounts relating to this collision. If you were driving in the area and were a witness, please contact police to assist our enquiries," Sergeant Davies said.

“I’m particularly keen to speak to anyone with a dash cam and who was driving in the area at the time in case they recorded any important footage."
