A man was taken to hospital with serious injuries after he was struck by a lorry.

Police are appealing for witnesses after a man was hit by a vehicle on the A414 near St Albans.

It happened at around 12.15am on Saturday February 15 between the Park Street roundabout and the London Colney roundabout.

The pedestrian, aged in his 20s, suffered serious injuries and was taken to hospital.

He remains there but police say he is in a stable condition.

The lorry driver involved stayed at the scene and is helping police with enquiries - and now Hertfordshire Constabulary is appealing for anyone with information to come forward.

Sergeant Mark Atkins, of the Bedfordshire, Cambridgeshire and Hertfordshire road policing unit, said: "We are appealing for any witnesses to come forward as a matter of urgency, to help us piece together the events leading up to the collision.

"This is a busy stretch of road, and we believe there would have been several people who drove past either immediately before or after the collision.

"If you did witness the incident, or have any information you think could assist our investigation, please get in contact. Alternatively, if you were in the area and have a dash cam fitted to your vehicle, please review the footage and send us anything you think could help with our enquires."

Anyone with information is asked to call 101 quoting reference 41/14220/20.
