Federal authorities announced on Apr. 7 an eight-count indictment against Emir Balat and Ibrahim Kayumi, charging them in connection with a terrorist attack that took place outside Gracie Mansion in Manhattan on March 7. The charges stem from an incident where the two allegedly carried out an ISIS-inspired attack using improvised explosive devices during protests near the official residence of the Mayor of New York City.
The indictment is significant as it addresses concerns about domestic terrorism and highlights law enforcement efforts to prevent mass casualty events. Authorities say that immediate action by police officers prevented further harm to civilians.
U.S. Attorney Jay Clayton said, “As alleged, just weeks ago, Emir Balat and Ibrahim Kayumi carried out a terrorist attack on the streets of New York. They sought to murder multiple innocent victims in the name of ISIS. The brave women and men of the NYPD responded immediately, and Balat and Kayumi were arrested on site.” Clayton added that evidence recovered included detailed plans for attacks found in a notebook as well as bomb-making materials from a storage unit.
FBI Director Kash Patel said, “These individuals allegedly prepared explosive devices and attempted to detonate them on the streets of New York in the name of ISIS, but their plan failed thanks to the brave police officers who acted quickly.” Patel emphasized continued partnerships among law enforcement agencies to protect citizens from acts of terrorism.
The indictment alleges that Balat and Kayumi traveled from Pennsylvania with explosives intending to cause maximum harm at protests outside Gracie Mansion. According to authorities, they threw one device toward protesters before attempting another near police officers; both were apprehended shortly after their actions.
Recovered evidence includes handwritten notes detailing bomb construction methods and alternate plans for attacks targeting public gatherings or using vehicles. Forensic analysis confirmed that one device contained triacetone triperoxide (TATP), described by officials as highly sensitive and used in previous terrorist incidents.
Balat faces additional allegations regarding statements pledging allegiance to ISIS following his arrest, while both defendants are charged with conspiracy offenses carrying sentences up to life imprisonment if convicted. The investigation involved multiple agencies including local police departments, federal task forces, U.S. Customs and Border Protection, Homeland Security Investigations, FBI field offices in Newark and Philadelphia, among others.
Clayton praised law enforcement’s coordinated response: “We…will continue to work every day to keep New Yorkers safe.”
As this case proceeds under Judge Vernon S. Broderick’s oversight in federal court, officials reaffirmed their commitment to holding those accused accountable while reminding that all charges remain allegations until proven.
