Monday morning turned tense at 26 Federal Plaza when an incendiary device went off outside the FBI’s New York offices, sending smoke drifting across Foley Square, triggering a shelter-in-place inside the towering federal complex, and ending with one person in handcuffs.
Officials say the FBI’s New York Joint Terrorism Task Force is now running an active investigation into what exactly happened and why.
How The Scare Unfolded
Video from outside the 41-story federal building showed smoke pouring into the open plaza as people rushed from the entrances and officers moved in. Law-enforcement sources told NBC New York that a man rolled a cart into the plaza loaded with fireworks and a flammable liquid, then set it off. Investigators later recovered what appeared to be a few airsoft rifles, according to the same report.
The NYPD Bomb Squad was called in to examine the cart as a precaution, and one person sustained a minor injury, NBC New York reported.
Lockdown In Foley Square
Police on scene described the device as a "makeshift incendiary device" built from fireworks and an ignitable liquid and quickly locked down the surrounding area out of caution, according to WABC. The building went into a shelter-in-place while officers secured the plaza.
The suspect was detained at the scene, and one person who suffered a minor injury was treated and declined further medical attention, WABC reported.
Witness video from Foley Square captured gray smoke rising from the plaza as federal and city officers converged, creating a surreal scene in one of downtown Manhattan’s most heavily guarded blocks.
FBI Takes Over
In a statement to WABC, the FBI said, "This morning an individual deployed an incendiary device outside of 26 Federal Plaza." The bureau confirmed the person had been taken into custody and that the FBI New York Joint Terrorism Task Force is handling the investigation.
Federal and local explosives technicians worked the scene to examine the device and make sure the plaza and surrounding area were safe before easing security measures.
Why This Location Matters
The incident unfolded at 26 Federal Plaza in Foley Square, a 41-story federal office complex that houses the FBI’s New York field office along with Immigration and Customs Enforcement, according to NBC New York. It is a familiar landmark at Worth and Lafayette streets, where federal operations and courthouse traffic collide with everyday downtown foot traffic.
Footage from the morning showed personnel hustling out of the building as smoke rose from the plaza, and the concentration of federal agencies on site prompted an immediate bump in security until the scene was cleared.
Part Of A Troubling Pattern
The scare arrives on the heels of a series of smaller incendiary incidents around the city earlier this month. In Queens, a number of Molotov cocktail attacks, including those targeting churches, were tied by federal prosecutors and the NYPD to a single suspect, as reported by CBS New York.
Those earlier cases caused limited property damage but nudged investigators into a heightened state of alert. Officials say they are now trying to determine the motive behind the 26 Federal Plaza incident and whether it has any connection to the prior attacks. They emphasize that the review is active and that coverage of the developing response is ongoing.
What Investigators Are Doing Now
Federal and city bomb technicians continued processing the plaza for evidence while the FBI New York Joint Terrorism Task Force coordinated the broader investigation, according to WABC. Officials have not publicly identified the suspect and have not yet announced any charges.
Authorities say the investigation remains very much in motion, and more details will be released once they are confirmed.
