Police are appealing for witnesses, information and dash cam footage following a "serious road traffic collision" on the A1(M).

Shortly after 6.15am yesterday (Monday 2 December), a green Renault Megane traveling on the northbound on the A1M between junction eight and nine, after overtaking a HGV entered a grass verge and lost control before hitting a barrier at high speed.

Emergency services attended, and the road was closed for an extended period of time.

Both the driver, a man aged in his 40s, and the passenger, a seven-year-old boy were taken to hospital with serious injuries.

Sergeant Luke Jenkins, from the Bedfordshire, Cambridgeshire and Hertfordshire Road Policing Unit, said: "Our enquiries are continuing, and I am urging anyone with information to please get in touch.

"If you saw anything, or have any further information, please contact police. Additionally, if you were driving in the area at the time and have a dash cam fitted then please check it as you may have recorded some crucial footage. This can be uploaded at https://herts.police.uk/dashcamupload).
