Dorset Police has issued a witness and dashcam appeal following a serious injury collision reported just after 9pm on 21 September in Poole Road, near to the St Michael’s Roundabout. The collision involved the grey Audi A4 estate and two pedestrians.

Emergency services attended and the pedestrians, a man in his 40s and a woman in her 30s, were taken to Southampton Hospital for treatment to serious injuries.

A grey Audi was located further down the road and it was reported that the driver was believed to have left the scene on foot.

Road closures were put in place as the emergency services responded and for an examination of the collision scene.

Sergeant Gareth Thomas, of the traffic unit, said: “We are conducting a detailed investigation to establish the full circumstances of this collision and I am keen to hear from any witnesses to the incident, or the manner of driving of the vehicle involved prior to it, as well as the movements of the vehicle and any occupants following the collision.
