PHILADELPHIA (CBS) – Philadelphia police and SEPTA police are trying to track a group of teenagers who caused extensive damage to two buses in Mayfair late Saturday night.

It happened near the intersection of Roosevelt Boulevard and Princeton Avenue at about 10:30 SEPTA spokesman Andrew Busch says the teens apparently just left an event nearby when they picked up rocks, bricks and anything else they could find and launched an assault on the buses that stopped to pick up and drop off passengers.

“One was a Route 14 bus, the other was a Route 50 bus and the vandalism ended up causing some physical damage to the buses. Some broken windows, some damage to the doors. Forntunately, there were no injuries to passengers or the operator on the bus.”

Busch says about two-thirds of the bus fleet have built in video cameras, and SEPTA police are working with Philly cops to first see if there were cameras on these buses then to see if they can figure out who did this.
