Feds Probe Alleged ISIS‑Inspired Bomb Plot at NYC Mayor’s Residence Protest
Federal prosecutors say 19‑year‑old Ibrahim Kayumi of Newtown, Pennsylvania, and 18‑year‑old Emir Balat drove from Bucks County to Manhattan and allegedly threw live homemade explosive devices into a March 7 protest outside Mayor Zohran Mamdani’s Gracie Mansion residence. Newly released video shows Balat being tackled by an NYPD officer moments after allegedly hurling a device, as someone in the crowd shouts "bomb," and officials say the recovered bomb contained TATP plus nuts and bolts taped on as shrapnel but failed to detonate. According to a criminal complaint, Balat told investigators he wanted the attack to be "bigger than the Boston Marathon bombing" and later allegedly wrote and signed a pledge of allegiance to the Islamic State at the precinct, prompting NYPD Commissioner Jessica Tisch to label the case an ISIS‑inspired terrorism investigation. The FBI says a search of a Langhorne, Pennsylvania, self‑storage unit linked to the case turned up explosive residue and required a controlled detonation, and surveillance footage shows Balat purchasing 20 feet of fireworks fuse at a Phantom Fireworks store in Penndel on March 2. The incident is stoking online arguments over protest security, lone‑actor terror threats, and how close an apparent ISIS‑inspired bombing attempt came to a large crowd outside the official residence of New York City’s mayor.
