Bomb squad crews safely detonated a possible explosive device at the house of a San Francisco Bay Area man and arrested him in connection with threats against Muslim people, a newspaper reported.
Officers in Richmond, Calif., received a tip that a man had said he wanted to harm Muslim community members, the Contra Costa Times reported.
Detectives said they learned the man might have made an explosive device at his home.
Authorities evacuated nearby residents Sunday before serving a search warrant at the man’s house and destroying the possible device. No one was injured.
On Monday, police identified the man as 55-year-old William Celli, a self-employed plumber.
