A San Francisco Bay Area man posted anti-Semitic threats in an online chatroom and threatened to commit a mass shooting at a synagogue, police said.
Authorities arrested 23-year-old Ross Farca, of Concord. He is charged with making criminal threats, possession of an illegal assault rifle and manufacturing an assault rifle, Concord police said in a statement posted to Facebook on Friday.
He pleaded not guilty at his arraignment, according to The East Bay Times. Bail was set at $125,000.
Concord police say the FBI found Farca’s comments online, which included threats to shoot law enforcement and claims that he had an assault rifle. He did not specify any locations.
