Teenager suffers 'potentially life-changing' injuries in crash with unmarked police car

A 19-year-old woman has been left with potentially life-changing injuries after a crash with an unmarked police car that was responding to an emergency in South Gloucestershire.

The police car was using blue lights and a siren at the time of the collision, which happened around 6.30pm on Sunday, Avon and Somerset Police said.

The teenager was treated at the scene by officers and paramedics and was taken to hospital with injuries "which are potentially life-changing", the force said.

The incident happened at a roundabout where the A4174 meets Badminton Road in Emersons Green, seven miles north of Bristol.

The woman's next of kin are aware and the force said it would support them.

The officers in the vehicle were not injured in the collision and will be offered welfare support.

The force said it has referred itself to the Independent Office for Police Conduct over the incident, as is standard procedure.
