A man has died after a crash between a car and a lorry - as police continue to try and track down the occupants of two vehicles who may have seen what happened.

As previously reported, a blue Mini Cooper and a blue Volvo articulated lorry crashed on the A30 near Sherborne on Tuesday.

Emergency services rushed to Babylon Hill, near to the junction with Marl Lane, at around 4pm and the driver of the Mini, a Yeovil man aged in his 20s, was taken by air ambulance to Southmead Hospital in Bristol with serious injuries.

Dorset Police has since confirmed the man died in hospital on Wednesday evening.

His family has been informed and are being supported by specially-trained officers, according to the force.

An off-duty nurse is thought to have stopped to help and police are hoping to trace them, along with the occupants of two other vehicles.

Sergeant Geraint Butler, of the serious collision investigation team, said: “Our thoughts are with the loved ones of the young man who sadly died, and officers are doing all they can to support the family at this extremely difficult time.

“We owe it to them to conduct a detailed investigation to establish the full circumstances of this collision and I would again urge any witnesses or anyone with relevant dashcam footage of the incident to please come forward.

“From our enquiries so far, we believe there were at least two vehicles in the vicinity whose occupants are likely to have witnessed what happened that we have so far not been able to trace. We would urge these people to please make contact with us.

“We also understand an off-duty nurse stopped to give assistance at the scene and we would be keen to speak to this individual and take their account.

“Furthermore, I would urge anyone travelling in either direction on the A30 between Yeovil and Sherborne around this time of the collision to please review any dashcam footage to see if they have captured anything of relevance, including the movements of the vehicles involved prior to the collision.”
