Mayor Eric Adams, Police Commissioner Keechant Sewell, the FBI and other agencies gathered at City Hall Monday to detail the multi-agency effort to stop a potential domestic act of terrorism on the Jewish community.

On Friday evening, the FBI and joint terrorism task force received information that there was a threat on an unidentified synagogue after the suspects allegedly made anti-Semitic and threatening posts on social media.

Those efforts led police in arresting two people at Penn Station on Saturday- suspects Christopher Brown from Aquebogue, New York and Matthew Mara from Manhattan.

Authorities seized a semi-automatic gun, a 30-round magazine, a laser light, a Nazi arm band and a black ski mask.

Brown and Mara are facing state charges of making a terroristic threat and criminal possession of a weapon, according to authorities.
