An HGV driver has been arrested on suspicion of drug driving after three people died in a collision on the A303.

Police were called just after 8.40am on 25 August to a report of a collision near Andover involving a Vauxhall Astra, a Mercedes food delivery van, an HGV and a DAF recovery truck.

Three people, all from separate vehicles, were pronounced dead at the scene.

Hampshire police said their families had been informed and were being supported by specialist officers.

The HGV driver, a 38-year-old man from Shropshire, was arrested on suspicion of driving a vehicle while unfit through drugs and causing death by dangerous driving.

He has been released under investigation while enquiries continue.

The police said it was now keen to hear from anyone who could assist its investigation into the circumstances of the collision.

DC Cate Paling, senior investigating officer at Hampshire police, said: “We are keen to speak with anyone who witnessed the collision, or the moments leading up to it, particularly anyone with dash cam footage.

“In the immediate moments after the collision, a small white car with a black roof passed the scene and we believe they may be an important witness who we wish to speak with.”
