Federal prosecutors charged Long Island, New York, with a man on Tuesday, claiming he built seven homemade bombs with the help of artificial intelligence, according to court documents.
The man, Michael Gunn, carried the bomb from Long Island to New York City, storing five and four shotgun shells on the roof of an apartment in the Soho area, officials said. He intended to combine the shotgun shell with one or more improvised explosive devices, they said.
On March 27, Gunn posted a message to President Donald Trump’s official X account, the indictment said.
“Dear @potus, I think it’s a shame that the walls were not built right here in New York, before the National Guard had to come here for protests and riots,” he was said to have written. “Or do you just drop a bomb on this place?
Five weeks later, Gann was arrested after posting on Instagram and then asked, “Want to go out and play like tomorrow?” According to authorities.
Cancer has not yet entered the plea and his lawyer declined to comment.
Order online
According to court documents, Gunn told law enforcement officials he used two household compounds ordered online to make improvised explosives. He also purchased over 200 cardboard tubes and over 50 feet of fuses. One of the devices he built had about 30 grams of explosive powder. It’s about 600 times the legal limit for consumer fireworks.
Officials said he appears to have acted alone and not as part of the group.
“The gun is said to have produced multiple improvised explosive devices intended for use in Manhattan,” said Christopher Leia, head of the FBI’s New York Field office. “The successful law enforcement partnership in New York allowed cancer to go to trial quickly before injuring innocent civilians.”

One of the witnesses, a US military veteran, said as Gann was mixing explosives from Inwood, the town of Long Island, he said, “What kind of veteran are you? I think you’re having problems in your neighborhood.
“Afterwards, cancer pointed to a Jewish school,” according to criminal charges filed at the time of his arrest.
The second witness agreed to call Gann while the FBI listened, according to the criminal charges. “He set ignited one of the devices near the East River on FDR Drive. The device exploded, scaring the cancer,” Gunn told the witness on one phone.
Witnesses said Gunn is considering disposing of the remaining five devices by throwing them into the river or putting them in the New York City Fire Department.
On June 5th, the day of the alleged appeal, law enforcement agents saw Gunn walking down the street with his shoulder bag, according to the lawsuit. When the agent identified himself to cancer, he told them he was heading to the fire station to unload the device, it says.
After reading his rights, Gunn told law enforcement officials that he “want to learn about chemicals that make fireworks and use artificial intelligence to purchase and mix them.”
Gunn first created four devices, and threw three from the Manhattan side of the Williamsburg Bridge. Two devices fell into the water, one fell on the train tracks and was retrieved nearby.
“The guns built an explosive device and stored it on the rooftop of Soho,” said Jay Clayton, an interim US lawyer.
