A pack of ATV riders struck two NYPD officers in Brooklyn Saturday and fled the scene, but one was caught, police said.

The officers were called to control a group of approximately 30 disorderly motorists on all-terrain vehicles and dirt bikes on Hicks Street and Old Fulton Street.

One of the motorcyclists bumped into the officer who was riding a scooter, causing the officer to fall and suffer injuries to his elbow and leg. His partner then stopped his own scooter to help him when a different motorcyclist struck his leg and knocked him down too.

The aggressive ATV rider then tried to circle around the right side but drove right over the policeman as he was lying on the ground. The mowed-down cop suffered back injuries. 

Both policeman were taken to Methodist Hospital and treated for their injuries.

The ATV rider was stopped at Nostrand Avenue and taken into custody, along with another rider from the pack, police said. Information about the rider and any charges filed against him weren't available.
