Police are trying to trace two cars involved in a collision in which a woman was injured.

Officers are appealing for witnesses to a road traffic collision on the A47 at West Bilney this morning.

They were called at 6am to reports of a collision between a lorry and a Vauxhall Astra. The female driver of the Astra was taken to hospital with minor injuries.

It is believed two other cars were involved in the collision but the drivers failed to stop at the scene – a Vauxhall Corsa and an unknown vehicle.

Officers are keen to trace both the Corsa and the other vehicle and are appealing for the drivers to contact them.

Anyone who saw the collision, or the manner of driving of any of the vehicles prior to the incident, should call PC Jeremy Blamire at Swaffham roads policing on 101.
