A man named as Andrew Arrabaca has been identified as the suspect accused of deploying an incendiary device outside a federal building in Lower Manhattan on Monday morning. The device was set off outside 26 Federal Plaza, which houses an FBI field office and a New York immigration court, prompting an investigation by the FBI New York joint terrorism task force. Law enforcement officers detained an individual at the scene shortly after the incident.

Two law enforcement sources told Fox News Digital that Arrabaca had "anti-ICE stuff" on him at the time of the alleged attack, though further details of his background and motive have not yet been disclosed. The FBI is continuing to investigate the incident, and no additional information about potential charges had been released at the time of reporting.
