An armed maniac lit an “incendiary device” outside a federal building in lower Manhattan early Monday in an anti-ICE attack being investigated by the terrorism task force, according to officials and sources.
The unidentified man started a fire outside of 26 Federal Plaza around 8:30 a.m., ignited fireworks and threatened passersby with airsoft rifles around 8:30 a.m., police and sources said.

Federal police took the perpetrator into custody at the scene — and found a cart with an anti-ICE message on it, sources said, with immigration agents among those who responded.
“This morning an individual deployed an incendiary device outside of 26 Federal Plaza,” the FBI confirmed to Fox News in a statement.
“The individual has been taken into custody and the FBI New York Joint Terrorism Task Force is investigating the incident.”

The man was pulling a cart containing to long firearms, more fireworks and other items, sources told The Post.
Three people, including two firefighters, suffered minor injuries during the incident and were taken to an area hospital, sources said.
The Jacob K. Javits Federal Office Building is home to New York’s ICE field office in Manhattan as well as offices for the US Department of Homeland Security, immigration court and other federal agencies.
The historic building became a hotbed of arrests and detention during President Donald Trump’s crackdown on illegal immigration last year.
