Car hits sprinkler system, floods San Francisco parking garage

A strange string of events occurred in San Francisco's Tenderloin neighborhood Monday morning.

A valet attendant left a red Mustang running while it was in reverse in a parking garage on Jones Street near O' Farrell Street.

The car went down a ramp inside a garage, hit a sprinkler system and flooded part of the floor.

At the same time, a Mercedes hit a fire truck parked outside.

Police say no one was injured in either incident.
