CRAZY VIDEO: Runaway city bus rolls backward down NYC street, slams into church

NEW YORK -- An empty MTA bus rolled down a Brooklyn block, striking several parked cars before crashing to a stop in front of a church.

The bus operator has apparently parked the bus and exited the vehicle just before 1 a.m. when it suddenly started rolling backwards.

One man who was attempting to change a tire on the street was forced to jump out of the way.

He was taken to Wyckoff Hospital for treatment of minor injuries. He was not struck by the bus.

The MTA employee was not injured. The reason the bus started to roll is under investigation.
