ANGIER, N.C. — A teenager was injured Saturday afternoon when an Angier police car crossed the centerline and hit her car head-on.

The police officer was responding to a motion-sensing alarm that had been activated at a location on South Dunn Street at 2:19 p.m., police said.

The officer, Travis Collis, was responding to the call when he ran his vehicle off the road and then -- while trying to gain control -- swerved back into oncoming traffic, police said.

He collided with a car driven by a 16-year-old girl near Old Buies Creek Road and Montague Road. The female driver was transported to an area hospital. The Angier Police Department has not released her name, the hospital she has been taken to or her condition.

Collins was airlifted to Duke Medical and is in stable condition with injuries in both legs.

The wreck is being investigated by the North Carolina Highway Patrol.
