Philadelphia.CBSLocal.com is reporting that a police officer was hit when a five vehicle accident occurred in Montgomery County on Thursday evening.

The crash site was at the intersection of Route 202 and South Henderson Road in Upper Merion Township.

Authorities say a police vehicle had stopped for a red light at the before mentioned intersection, when their unit was hit from the rear.

The resulting impact drove the police vehicle into the back of another vehicle, causing the unit to cross the center median. The chain-reaction crash eventually resulted in five damaged vehicles.

The police officer and two others were received by area hospitals. While the officer was released, the condition of the two others is not known at the present time.

The accident investigation continues.
