COOLBAUGH TOWNSHIP, PA - At least nine people were injured when a bus driven by a Brooklyn man flipped over in Pennsylvania Friday, according to police.

It happened around 2:30 a.m. on Route 423 in Coolbaugh Township.

Police say the bus rolled over trapping at least one teenager inside.

Firefighters extricated the teen from the overturned bus, and say at least eight other teenagers were transported to the hospital for treatment.

A child was also airlifted to Lehigh Valley Medical center for serious injuries.

The man driving the bus has been identified as 32-year-old Bernard Zitronenbaum, of Brooklyn.

Police say Zitronenbaum was driving north on Route 423 when he failed to properly navigate around a right curve, causing the bus to roll onto its driver's side and slide on the roadway.  

He was transporting the boys from the Sanz Klausenberg Summer Camp in Woodbourne, New York, where they had been on a trip.
