Police officers have been criticised after a man injured in a car crash went undiscovered - lying in a ditch.
A member of the public found the man several hours after the crash on the A47 near Wisbech in July last year.
Following an investigation, the Independent Police Complaints Commission, concluded officers from Norfolk Police could have conducted a more thorough search.
The man's damaged car was reported to police who attended the scene but after identifying the car's owner and searching the area, the officers left, leaving a 'police aware' sticker on the vehicle.
The man was to the Queen Elizabeth Hospital in King's Lynn with life threatening injuries. He survived but is still recovering from his injuries.
Norfolk Police has apologised and "management action" has been taken against the officers involved.
