A Gardena councilman has been arrested after his car struck a police officer at the scene of a traffic accident in Hawthorne. Police say two-term Councilman Steven Bradford was attempting to bypass police when he struck the officer yesterday. After the arrest, Bradford told a Hawthorne police watch commander that he was a city councilman. Gardena City Manager Mitch Lansdell declined comment on the arrest. Hawthorne, which neighbors Gardena, is about 15 miles south of Los Angeles.
