A motorist has suffered a serious head injury after a crash which resulted in his van flipping onto its roof in Potters Bar.

The white Volkswagen Caddy was travelling northbound in Barnet Road when the incident happened around 1.15am on November 15.

As it passed the junction with Dancers Hill Road, it collided with a central pedestrian refuge before crossing to the near side and rolling onto its roof, Hertfordshire Constabulary said.

Both the driver and passenger managed to escape from the car and the emergency services were called to the scene.

The passenger only sustained minor injuries, however the driver – a man in his 20s, sustained a serious head injury and remains in hospital.

Officers are appealing for information, witnesses and dash cam footage of the incident.

PC Scott Lewsey, from the Bedfordshire, Cambridgeshire and Hertfordshire Road Policing Unit, said: “We are appealing for anybody who saw the collision, or the events leading up to it, to get in touch. If you have any information at all, please don’t hesitate to contact us.

“I would also like to ask anyone who was driving through the area at the time and has a dash cam fitted to their vehicle, to please check it. If you spot something that could help our investigation, please get in touch straight away quoting ISR 32 of 15 November.”
