A 51-year-old San Francisco man with an “interest in white hate groups” has been charged with one bombing and three bombing attempts in the city over the last five months, the FBI announced.

Coy Ray Phelps was not accused of the bombing attempt last Monday at a rabbi’s home, but he is charged with two other incidents the same day. The FBI indicated that it might file additional

charges against Phelps, who was denied bail. Raymond A. Mislock Jr., the San Francisco FBI’s acting special agent in charge, said Phelps was not armed when he was arrested about noon

Friday. Agents said that Phelps’ garage, at his north-central San Francisco home, yielded hate literature and rounds of ammunition but no explosives. MORE TO READ
