Officers say that at about 10:00 p.m. Tuesday, someone pulled the bus out of the All City Transportation bus yard, located at 68th Street and Norwitch Drive in Southwest Philadelphia.
The suspect then went on a short joy ride that ended early Wednesday morning when he failed to negotiate a turn at the corner of 68th Street and Buist Avenue.
The bus slammed into a parked car there. The suspect then jumped out of the bus and ran off.
Police are examining surveillance video at the bus yard to see if they have a good image of the thief.
This is the second school bus theft in Philadelphia this week. The first instance happened on Monday afternoon when three teens stole a bus from a lot in Kensington while the bus driver attended a funeral.
The search for the teens continues.
