The man accused of setting off fireworks and lighting a fire Monday morning in front of a New York building housing an immigration court and other government offices is a former U.S. Army soldier, an FBI official said. Andrew Arrabaca, who was a mechanic on Patriot missile systems, is in custody and has been interviewed, said James Barnacle, assistant director in charge of the FBI’s New York Field Office. Barnacle said at a news conference that the 43-year-old Arrabaca “came armed with bad intentions” and had various weapons, including a pellet gun, knives, a hammer and a machete. Arrabaca fired five to seven pellets from an airsoft rifle toward the building, he said. “He is an anti-American, anti-government extremist,” Barnacle said. No charges have been announced yet against Arrabaca, and it was not immediately clear if he has a lawyer. As the flames erupted outside an entrance to the building at 26 Federal Plaza, the person was tackled by a security officer and taken into custody, video shows. The lower Manhattan building, 26 Federal Plaza, has become a focal point for demonstrations against the immigration policies of President Donald Trump’s administration.
