10-car chain-reaction crash including a police cruiser miraculously hurts no one on icy 6th Avenue in Denver, Colorado

A Denver patrol car was hit by another car triggering a 10-car chain-reaction collision on eastbound 6th Avenue near Federal Boulevard early Saturday morning, according to police. The parked patrol car was struck after it responded to an accident that happened around 7 a.m., said Denver police spokesman. The police officer was not in the car at the time and was not harmed. No serious injuries have been reported in any of the accidents. Jackson said that immediately after the officer's patrol car was hit, another car hit the second vehicle and kept on going. Police are looking for that hit-and-run driver and a second driver who swerved to avoid a jumble of vehicles and hit the concrete median, Jackson said. Another car crashed nearby on westbound 6th Avenue, according to police. "Very icy there," police said in a Tweet. Both directions of 6th Avenue were reopened around 9 a.m. after they had been closed for two hours.
