United States Attorney for the Southern District of New York, Jay Clayton, announced charges against Michael Gann. Gann is accused of manufacturing at least seven improvised explosive devices (IEDs) using chemicals ordered online. These devices were allegedly stored on rooftops in the SoHo neighborhood of Manhattan and one was thrown onto subway tracks.
“The safety of New Yorkers is paramount,” said U.S. Attorney Jay Clayton. “As alleged, Michael Gann built explosive devices, stored them on a rooftop in SoHo, and threw one onto the subway tracks—putting countless lives at risk.”
FBI Assistant Director Christopher G. Raia highlighted the collaboration among law enforcement agencies that led to Gann’s swift arrest before any harm could occur. “Michael Gann allegedly produced multiple improvised explosive devices intended for use in Manhattan,” Raia stated.
NYPD Commissioner Jessica S. Tisch praised the investigative work that prevented potential harm from these explosives. “This defendant allegedly stockpiled homemade explosives and traveled to New York City with these deadly devices,” she said.
According to court documents, Gann ordered precursor chemicals and assembled IEDs between May and June 2025. He conducted internet searches related to explosives and firearms during this period.
Gann faces several charges including attempted destruction of property by means of explosives, transportation of explosive materials, and unlawful possession of destructive devices. The potential sentences range from five to twenty years depending on the charge.
Jay Clayton acknowledged the efforts of various law enforcement bodies involved in this case including the FBI’s Joint Terrorism Task Force, NYPD, Bureau of Alcohol, Tobacco, Firearms and Explosives, Nassau County Police Department, and others.
The prosecution is being handled by Assistant U.S. Attorneys Jonathan L. Bodansky, Michael D. Lockard, Chelsea L. Scism, along with Special Assistant U.S. Attorney Julie Isaacson.
