Dramatic footage has emerged of a car knocking a man over after another climbed onto the vehicle's bonnet during Le Mans 24 hours race.

The video, captured on June 16, shows one man clambering onto the front of a car, prompting the driver to accelerate.

With the driver's vision obscured, the car then hits another man standing in its path, knocking him over.

According to the filmer, the man suffered a nose bleed and grazing to his right elbow.

"The police were called and they came in about six vans and shut Mad Friday down. No arrests were made because blame could not be placed on anyone," the filmer wrote online.
