Nurses and security staff who had just finished a gruelling night shift at a hospital found their cars and scooters damaged as they left work on Christmas Eve morning.
Most of the vehicles parked on as estate near the Royal Derby Hospital were damaged in a flurry of seemingly random attacks.
Security officer Micky Williams returned from a 12-hour shift at 7am to find a nurse examining his car, having thought the damage to his wing mirror had been caused by her scraping past it.
