TWELVE people were involved in a four-car crash on the M5 as one injured woman trapped inside her vehicle had to be freed by firefighters. 

The incident happened on the M5 northbound between junctions 7 (Worcester South) and 6 (Worcester) at around 2.30pm on Friday (March 15).

The M5 was closed northbound between those junctions due to the multi-vehicle collision with motorists diverted onto the A4440.

Drivers faced delays of an hour even when the motorway reopened later that afternoon. The fire service said four cars were involved, and police and ambulance said three cars.

"Upon arrival we found a woman who was the driver of a car. She was extricated from the vehicle by the fire service.
