A northern California man was arrested over the weekend for allegedly plotting a mass shooting attack against Jews.

Ross Anthony Farca, 23, of the town of Concord was caught by local police in collaboration with the FBI, the San Francisco Chronicle reported on Saturday.

The arrest was reportedly the result of a tip from someone who saw threatening messages posted by Farca on a gaming website.

Farca has an obsession with Nazism and embraces a violently antisemitic ideology. A search of his home following the arrest revealed that he possessed books on Nazism and the Hitler Youth, as well as an assault rifle and ammunition.

He was apparently planning a copycat attack similar to the shootings at the Tree of Life synagogue in Pittsburgh in October and the Poway Chabad synagogue in California in late April. He also regarded the man who killed 51 Muslim worshipers at a mosque and Islamic center in Christchurch, New Zealand as a hero.

Detectives were also able to obtain an emergency Gun Violence Restraining Order against Farca to prevent him from legally purchasing any more firearms, the Chronicle said.

Farca reportedly intended to wear a Nazi uniform while carrying out his planned attack.
