Officers investigating a serious injury road traffic collision in West Moors are appealing for witnesses or anyone with relevant dashcam footage to come forward.

At around 5.55pm yesterday a collision occurred on Station Road, outside West Moors Library. It involved a pedestrian and a blue Ford Fiesta, which was travelling south toward Ferndown.

Officers attended the scene, along with the ambulance service, and the pedestrian – a woman aged in her 90s – was taken to Southampton Hospital with serious injuries. Her condition is believed to be life-threatening and her family has been informed.

The driver of the Ford Fiesta, a 45-year-old local man, has been arrested on suspicion of driving offences and is assisting officers with their enquiries.

Road closures have been put in place so that the emergency services can respond to the incident and officers can carry out a full examination of the scene as well as further enquiries.

Sergeant Lee Savage, of the traffic unit, said: “We are carrying out a full investigation into this collision and I would urge any witnesses or anyone with relevant dashcam footage to please contact us.

“Our initial enquiries indicate there are likely to have been a number of vehicles in the area around the time of the collision whose occupants may have witnessed what happened or that may have caught something of relevance on dashcam.

“These vehicles may include a black Mercedes convertible, a white Ford Transit van, a silver Vauxhall – possibly a Mokka, a black Audi and a white Volkswagen Scirocco as well as a red Range Rover Evoque that was parked nearby.

“Finally, I would like to thank members of the public for their patience and understanding while the road closures are in place. These are absolutely necessary to allow the emergency services to respond to the incident and for an examination of the scene to be safely carried out.”
