Man Detonates Incendiary Device Outside Federal Building Housing FBI and Immigration Courts in Manhattan

BLUFAnti-ICE grievance has now crossed from protest disruption into premeditated armed attack on a federal facility, establishing immigration enforcement sites as a persistent lone-actor target set.

Andrew Arrabaca, 43, a former Army mechanic who served on Patriot missile systems from 2001 to 2005, poured gasoline outside 26 Federal Plaza, ignited it with a lighter and a large firework, and fired five to seven pellets from an airsoft rifle toward the building on Monday morning, according to FBI Assistant Director in Charge James Barnacle 12. Two government employees and one civilian, an immigrant arriving for an immigration hearing, suffered minor injuries 12. Federal Protective Service officers tackled Arrabaca and took him into custody; investigators recovered two axes, a hammer, a machete, three knives and additional incendiary devices along with a cart bearing "ICE Off Our Streets" signage and anti-ICE literature, NYPD Commissioner Jessica Tisch and Barnacle said 12. Barnacle said Arrabaca told investigators after his arrest that he was targeting the building and was "okay" if he hurt or killed people entering it, federal or civilian 12. The FBI's New York Joint Terrorism Task Force is investigating; charges had not been filed as of Monday afternoon 2.

Analysis
Federal immigration facilities are now an explicit target set for lone-actor grievance violence rather than a backdrop for protest, and Arrabaca's stated willingness to kill anyone entering the building, combined with the axes, machete, extra incendiaries and prior military background, points to premeditation beyond a spontaneous outburst. Reporting across CNBC, ABC, Axios and Gothamist traces to a single FBI/NYPD briefing rather than independent verification, though the convergence supports confidence in the core facts. Federal Protective Service's rapid response averted casualties, strengthening the case for on-site armed protection at comparable ICE-linked buildings nationwide. An isolated individual acting on personal grievance, rather than a coordinated extremist campaign, remains a plausible competing explanation, and whether this reflects broader mobilization is genuinely uncertain.
