PENN TOWNSHIP, Pa. (CBS) – Two Pennsylvania State Troopers were knocked unconscious during a fiery car crash in Chester County early Friday morning.

The crash happened at about 5:30 a.m. near Kelton Road in Penn Township, Pennsylvania.

According to investigators, both Troopers were in the same car and were responding to a burglary in progress.

While turning on a curve in the road, the patrol car left the roadway and slammed into a tree head-on.

Both Troopers were knocked unconscious and were entrapped within the vehicle, which immediately caught fire, and fully engulfed the front portion of the vehicle.

Assisting Troopers, who had been responding to the same robbery, stopped to render aid and were eventually able to extinguish the flames by using fire extinguishers from patrol vehicles and by running to neighboring homes to retrieve buckets filled with water.

Rescue crews were able to extricate the troopers by removing the roof of the vehicle.

The Troopers were taken to Christiana Hospital in Delaware to be treated for serious, but non-life threatening injuries.

The names of the Troopers were not immediately released pending notification of family members.

The crash remains under investigation.
