SAN FRANCISCO (AP) - San Francisco’s police chief says an off-duty officer who shot and grazed a motorist following a fender bender opened fire in self-defense after the man punched her.

Chief Greg Suhr told the San Francisco Chronicle (http://bit.ly/1hPMSrY) an off-duty San Francisco firefighter witnessed the crash early Sunday morning between the motorist and the officer on Interstate 280. The firefighter said the sergeant identified herself as a police officer after she and the motorist pulled into a gas station, but the motorist said he did not care and punched her.

Police said the sergeant fired in self-defense, and particles or debris from the round, which hit the ground, struck the man in the ankle. He refused medical treatment and was booked on suspicion of attacking the officer.

Neither the officer nor the suspect has been identified.
