Passers-by unite to rescue trapped motorcyclist

A crowd of nearly a dozen people have overturned a car to rescue a motorcycle driver trapped beneath.

The crash happened near Utah State University in the US when a driver crashed into a motorcyclist who then lost control of his bike and slid under the car, his motorcycle erupting in flames.

Witnesses rushed to the scene and spotted him beneath the car and together were able to flip the BMW and drag the man to safety.

The 21-year old motorcyclist suffered broken bones, cuts and burns.
