Following a fatal road traffic collision on the evening of Saturday 16 September, police officers are appealing for anyone with relevant dashcam footage to come forward.

Reports that the vehicle involved, a blue BMW 1 Series, had left the carriageway and sustained extensive damage were received just after 9.30pm.

Emergency services attended and very sadly an 18-year-old female passenger was pronounced dead at the scene. The three other occupants of the vehicle were taken to hospital, one is believed to have sustained serious injuries and the other two are believed to have sustained minor injuries.

Two men and a woman, all aged 18, were arrested on suspicion of driving offences.

Sergeant Mile Gatfield, of the traffic unit, said: “Our thoughts are with the family of the young woman who sadly died, and officers are supporting her family.

“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.

“I would also urge anyone who may have captured any relevant dashcam footage to please contact us.”
