POLICE investigating a road traffic collision are appealing for the driver of a "sporty" Mercedes to assist their enquiry.

They believe the Mercedes was overtaken by a car that was later involved in the collision.

The incident happened on the A372 Westonzoyland Road, Bridgwater, at about 10pm on Wednesday, January 26.

The collision involved two BMW X1 cars, one gold and the other one white.

The driver of the latter vehicle suffered a broken ankle.

An Avon and Somerset Police spokesperson said: "The gold BMW had reportedly overtaken another car just before the collision.

"Officers are grateful to a witness who came forward following an earlier appeal to report seeing a white Mercedes with a “sporty sloping back” in the area at the time.

"If you were driving the car that was overtaken, or if you have any dashcam footage which could help, please get in touch."

If you can help, call police on 101 and give the call handler the reference number 5222021203, or complete the Avon and Somerset Police online appeals form.
