Norfolk Police are appealing for witnesses after a man fell from a moving car in Stalham yesterday morning.
At 8am a red BMW 1 series was travelling in the direction of North Walsham from Great Yarmouth when a man was seen to leave the passenger side of the moving vehicle. He ended up on the A149 near Richardson's boatyard.
Members of the public came to his aid until the East of England Ambulance Service arrived. He was then taken to Addenbrookes hospital with serious injuries and remains there in a critical condition.
Officers are keen to trace two men who stopped at the scene to assist with the man's injuries.
