Californian Jews are on heightened alert after a man who had spoken of his plans to murder Jews was released on bail just days after his arrest earlier this month. 

Ross Farca, of Concord, California, boasted on a gamer website that he wanted to kill dozens of Jews and livestream the attack as he did so, mimicking the actions of the far-right terrorist who killed more than 50 people in attacks on two mosques in Christchurch, New Zealand, in March.

But despite being arrested in early June, Mr Farca, 23, was released on bail just days later, and is now contesting an order which prevents him from having access to firearms.

According to the Jewish Telegraph Agency, the Jewish Vocational Service in San Francisco has circulated a mugshot of Farca, warning people to contact the police if they spotted him. Other congregations have boosted their security.

According to a police report, Farca, who used the screen name “Adolf Hitler (((6 million)))”, described how he had “a fully semi automatic weapon AR15 with multiple high capacity magazines”, and talked about his intention to kill “clusterf***s of k*kes.” He wrote that he planned to carry out such an attack while “wearing a Nazi uniform” and would livestream it, adding “Nazi music.” He described how he would kill more people than a shooting at a Chabad synagogue in Poway, California, in April, in which one person was killed and three injured.

“Wanna see a mas[s] shooting with a body count of over 30-subhumans?” Farca asked. He estimated that he would probably be able to kill “like 30 k*kes and then like five police officers, because I would also decide to fight to the death.”

A police search of Farca’s residence discovered an illegally assembled AR15 assault rifle, a number of high capacity magazines, and “Nazi literature”. 

A number of Jewish residents had attended the hearing during which Farca was released on bail, with one man describing the sense of “helplessness” as they watched him walk free. 

Farca is currently subject to an emergency order preventing him from access to guns, which expires on Monday. He is contesting a new order from the local police department seeking to extend that gun ban for another two weeks. He is not due back in court until July 30.
