A chilling discovery in the heart of America’s biggest city has left residents shaken and federal investigators on high alert. Authorities say a man quietly built and hid homemade bombs around New York City — not overseas, not in some distant conflict zone, but right here, among the millions who walk the streets every day. The news dropped like a jolt, leaving people wondering how close the city came to a headline no one ever wants to read.
Michael Gann, 55, was charged on Tuesday after federal investigators say they uncovered a series of improvised explosive devices stashed in locations that thousands of people pass daily. According to prosecutors, his targets weren’t isolated. They were right in the middle of everyday life: the Williamsburg Bridge, active subway stations, even residential rooftops in busy neighborhoods. Authorities say Gann used chemicals purchased online, assembling at least seven devices and hiding them in plain sight.
What stands out is how close this came to a disaster. Investigators allege Gann didn’t just stockpile explosives — he deployed one, throwing it onto the subway tracks. Imagine the surge of commuters, the crowded platforms, the trains rushing by. The thought of what could have happened lingers like a shadow over the city’s morning routine.
“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,” U.S. Attorney Jay Clayton said. “Thanks to swift work by our law enforcement partners, no one was harmed. That vigilance assuredly prevented a tragedy in New York.”

The word “vigilance” carries weight here. Because this wasn’t a plot that fizzled out before it started. Authorities say it was active, moving, spreading across the city. And for a brief moment, Gann was already in custody. He had been arrested in June after being caught with another device. But court records show he was released soon after. That same day, he posted online: “wants me to go out to play like no tomorrow?”
It is unclear how investigators first connected the dots. But once they did, the picture was grim. Bombs on rooftops. Bombs on bridges. Bombs near people heading home from work or kids riding the subway to school. The details read like something from a crime thriller, except this was real life playing out in real time.

FBI Assistant Director Christopher Raia praised the quick teamwork that led to Gann’s capture, calling it an example of agencies moving fast to stop what could have been catastrophic.
The devices are now in federal custody. The investigation is still unfolding.
