POLICE would like to speak to drivers who may have witnessed a collision on the A303 early this morning involving a pedestrian and two vehicles.

Officers were called just before 2.40am after a 24-year-old woman from Kempshott was involved in a collision with a Mercedes box van and a Volvo heavy goods vehicle on the eastbound carriageway, just outside of Andover.

It is understood a Mercedes Sprinter van had narrowly avoided a collision with the woman just minutes beforehand.

The woman is being treated for serious injuries as a result of the collision - anyone with any information is asked to contact Sergeant Brown at Whitchurch Roads Policing Unit on 101.
