Four Boston police officers investigating a report of a man with a gun have been taken to the hospital after two were dragged and two were narrowly missed by a fleeing car.

Superintendent Randall Halstead says two plainclothes officers approached the vehicle in the city's Dorchester neighborhood at about 12:30 a.m. Wednesday. As they tried to speak to the driver, the vehicle sped away, dragging the two officers.

Two uniformed officers providing backup were narrowly missed by the fleeing vehicle.

None of the injuries is considered life-threatening. The officers' names were not immediately made public.

Police are still looking for the vehicle, they describe as a gray or silver Chevrolet, possibly with Connecticut plates.
