A 61-year-old woman driving a Vauxhall Astra was killed when her vehicle was in collision with a Vauxhall Insignia on the A35 at Holmsley yesterday.
The woman, who came from Christchurch, Dorset, died at the scene. Her passenger, a 39-year-old woman from Lee-on-the-Solent, suffered minor injuries and was treated at the scene.
The Insignia was being driven by a 52-year-old Southampton man who also suffered minor injuries but was taken to Southampton General Hospital as a precaution.
Today police revealed that he had been arrested in connection with the crash, which occurred at the junction of the A35 and the B3058 Holmsley Road.
Officers are appealing for witnesses to the collision. They are particularly keen to hear from the driver of a blue Volvo estate that was travelling along the A35 at Holmsley when the crash happened just before 10am.
Call Sergeant Andy Lynch at the road death investigation team on 101, quoting Operation Armel.
