FOUR people were injured during a crash involving a fire engine last night.

An appliance belonging to Buckinghamshire Fire and Rescue Service was involved in a collision with two cars on the A40 at Denham just after 6.30pm.

Another two fire engines - from Beaconsfield and London - were then called to the scene. Three men and a woman, all of whom sustained injuries, were freed by firefighters.

An investigation into the cause of the collision is being carried out internally by Bucks Fire and Rescue.
