Hours after issuing a rare warning about a security risk at New Jersey synagogues, the Federal Bureau of Investigation identified a man who holds “radical extremist views,” and who they say was the source of the threat, a federal official told faith leaders Friday morning.
It was not clear if a suspect was in custody, but officials said the threat had been “mitigated.”
“He no longer poses a threat to the community at this time,” James E. Dennehy, the special agent in charge of the F.B.I.’s Newark office, said during a morning conference call with state and federal law enforcement officials and more than 500 Jewish leaders.
Mr. Dennehy said investigators believed that the man, who is from New Jersey, was acting alone, but they are continuing to pursue leads about people he might have been in contact with. The man was not publicly identified, and officials offered no additional information about whether he had been charged with a crime.
He was located Thursday night, officials said, and questioned for a “few hours.”
“He expressed radical, extremist views and ideology, as well as an extreme amount of hate against the Jewish community,” Mr. Dennehy said.
Incidents of harassment and violence against Jews and Jewish institutions have increased nationwide and have only intensified as celebrities like the rapper Kanye West, who goes by the name Ye, and the basketball player Kyrie Irving, have come under fire for antisemitic posts on social media.
