Gracie Mansion attack arrests

Federal authorities arrested two teens from Bucks County, Pennsylvania — 18-year-old Emir Balat and 19-year-old Ibrahim Kayumi — after alleging they planned and attempted an 'ISIS-inspired' attack near Gracie Mansion, the New York City mayor's residence. Sources say the arrests followed an incident in which the pair were charged after allegedly throwing an improvised explosive device at Gracie Mansion during a violent weekend protest. The teens were arrested March 7 and indicted March 9 on federal terrorism charges.

TATP device and charges

Authorities say the device involved highly unstable triacetone triperoxide (TATP) — reportedly made from sports-drink bottles — a compound often called "Mother of Satan." Federal prosecutors have charged the teens with a range of explosives and terrorism-related offenses. The Buckeyes Wire listing of charges includes "use of a weapon of mass destruction" among counts such as transportation and receipt of explosive materials and unlawful possession of destructive devices.

Alleged ISIS-linked motivations

Unsealed court documents and law-enforcement sources cited in reporting say the two admitted viewing ISIS propaganda and described motivations tied to extremist ideology and local political clashes. The New York Post reported that the pair 'admitted to officers that they watched ISIS videos, had self-radicalized, and targeted right-wing demonstrators.'

Buckeyes Wire quotes investigators saying Balat wanted an attack 'even bigger' than the 2013 Boston Marathon bombing. Buckeyes Wire also reported that Kayumi 'reportedly claimed affiliation with ISIS, said he had viewed ISIS propaganda, and allegedly supplied the explosive.'

Teens' travel under probe

Reporting highlights overseas travel. Investigators are probing whether the trips indicate self-radicalization or external recruitment.

The New York Post says Balat spent "more than three months in Istanbul last year" while Kayumi traveled "to Istanbul and Saudi Arabia in 2024 and to Melbourne in 2019." Buckeyes Wire notes federal investigators are examining the teens' travel history to determine whether they were self-radicalized or recruited.

Indictment and community fallout

Coverage reports on the legal and community aftermath of the case. The indictment includes counts for providing material support to a designated foreign terrorist group. Federal and local law enforcement executed searches of suburban homes.
