A former US Army soldier has been arrested after allegedly setting fire to the entrance of a federal building in lower Manhattan while shouting anti-government and anti-ICE statements, according to the FBI. The building, 26 Federal Plaza, houses offices for the FBI, Immigration and Customs Enforcement (ICE) and US Citizenship and Immigration Services, and has become a focal point for protests against President Donald Trump's immigration policies, making the attack particularly sensitive given ongoing tensions around ICE operations.

The suspect, named as 43-year-old Andrew Arrabaca of Poughkeepsie, New York, allegedly fired five to seven pellets from an airsoft gun towards the building, set off fireworks, then poured an accelerant on the entrance steps and ignited it before being tackled by a security officer. He was also found carrying two axes, a machete and three knives. Three people were injured, including two government employees and an immigrant attending a status hearing, though all injuries were minor. Arrabaca served in the regular Army from 2001-04 and the Army National Guard from 2004-05 with no deployments; FBI officials described him as an "anti-American, anti-government extremist", while New York Mayor Zohran Mamdani called the incident "deeply disturbing".
