Authorities say a small fire that damaged a Planned Parenthood facility in Southern California was apparently ignited when someone tossed a container with a flammable liquid through a window.

Ventura County Fire Capt. Mike Lindbery says it smelled like gasoline at the scene of the arson late Wednesday in Thousand Oaks. No injuries were reported.

Sheriff's Capt. John Reilly says a suspect wearing a hooded sweatshirt and a face mask was recorded by surveillance cameras.

A rock was used to shatter the window.

Crews arrived to find the building's sprinklers had extinguished most of the flames.

Lindbery says there was more damage from the sprinklers than from the fire itself.

Planned Parenthood didn't immediately return a call for comment. Reilly didn't know if the facility would open on Thursday.
