A Taneytown police officer suffered minor injuries Sunday night after his patrol car was dragged for almost a mile by a pickup truck.
Pfc. Edward Engel said he received a complaint about an assault and battery in the 4300 block of Nusbaum Road about 9:35 p.m.
The officer was told by witnesses that a man had assaulted two people and threatened to return with a shotgun, police reported.
Patrolman Engel waited along East Baltimore Street to look for the truck, which a victim identified as it passed.
The officer chased the truck and the suspect accelerated to 75 mph in a 25 mph zone.
The truck turned east on Sells Mill Road and south on Basehores Mill Road, where it stopped suddenly. The patrol car struck the rear of the truck and the bumpers locked, police said.
Patrolman Engel said he disengaged the vehicles, but as the truck headed north on Unger Road, the vehicles locked again, dragging the police car behind it.
Patrolman Engel said when the vehicles separated the second time, the truck spun and was hit by the patrol car.
Officers arrived and apprehended the suspect, who was taken to Carroll County General Hospital, but refused treatment and left the hospital.
The officer was treated at the same hospital for a sprained wrist and contusions of the face, apparently from the air bag, which inflated when the car hit the truck.
Investigators said they consulted with the state's attorney's office and placed multiple charges against William Joseph Iser, 25, of Littlestown Pike.
Police have obtained a warrant for his arrest.
The patrol car was extensively damaged, said Taneytown police Chief Mel Diggs.
