A woman in her 90s was taken to Southampton Hospital with what are believed to be life-threatening injuries following a collision with a blue Ford Fiesta at around 5.55pm on Tuesday 4 May on Station Road, outside West Moors Library.

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