A newly released criminal complaint says that the two teenagers accused of throwing an explosive device near the mayor of New York City’s official residence pledged their allegiance to ISIS over the weekend.

After being arrested on Saturday, March 7, 18-year-old Emir Balat was caught on officers’ body-worn cameras saying, “This isn’t a religion that just stands when people talk about the blessed name of the prophet,” according to the criminal complaint released Monday.

“If I didn’t do it, someone else will come and do it,” Balat said in the back of the NYPD car, the complaint explained. “All praise is due to Allah, Lord of all worlds! I pledge my allegiance [sic] to the Islamic State.”

Officials said that 19-year-old Ibrahim Kayumi admitted to watching ISIS propaganda on his phone, was partly inspired by ISIS and that, “he did not feel comfortable holding the devices earlier that day.”

NYPD Police Commissioner Jessica Tisch said that Balat, who is a student in the Neshaminy School District, threw the explosive device near Gracie Mansion on Saturday, March 7, causing flames and smoke to travel through the air before hitting a barrier.

“Mr. Balat lights the device and starts running with it. He then drops the device,” Tisch said.

After the first explosive device was thrown, Tisch said that Balat ran to grab a second explosive device from Kayumi, who has ties to Newtown Township. However, Balat was unable to throw the second device and both were taken into custody at the scene.

NBC10 went to an address in Langhorne, Bucks County, on Sunday, March 8, to ask about Balat but the person who answered the door said he was not there and declined to comment or share any information about possible legal representation for Balat.

NBC10 was also outside a home in Newtown on Sunday night when someone was taken away in handcuffs and the FBI went inside to search the home in connection to the incident.

“I can confirm the FBI is conducting court authorized law enforcement activity,” a spokesperson told NBC10. “I would have nothing additional to provide.”

The FBI was also carrying out a search warrant in Middletown Township, Bucks County, in the area of Durham and Frosty Hollow roads on Sunday night, police there said.

An FBI spokesperson told NBC10 that they are conducting interviews with people who knew the two suspects in Pennsylvania as well on Sunday.

A bomb squad analyzed the explosive device thrown and found that it was an improvised explosive device that could have caused serious bodily harm or injury, Tisch had said.

The criminal complaint released on Monday explained that Balat was carrying a Pennsylvania driver’s license that had his picture on it, his name and a Pennsylvania address.

After Balat and Kayumi were arrested, officers found a parked car that had New Jersey plates. When they checked the automatic license plate readers, they found the vehicle had driven east from New Jersey before getting onto the George Washington Bridge’s upper level to enter Manhattan, the complaint said.

Police have said that Balat and Kayumi were in the area with a large number of counterprotesters to conservative influencer Jake Lang’s protest, called “Stop the Islamic Takeover of New York City, Stop New York City Public Muslim Prayer.”

Overall, six people were arrested as a result of Saturday’s protest, including Balat and Kayumi, a person who deployed pepper spray and three others related to disorderly conduct and obstructing traffic, Tisch said.

Ian McGinnis, of Philadelphia, was among the other four arrested not in connection to the explosives, according to court records. He faces charges including assault, unlawful reckless endangerment and unlawful possession of noxious matter.

New York City Mayo Zohran Mamdani and first lady Rama Duwaji, who are Muslim, were home at the time of the commotion.

“Violence at a protest is never acceptable,” Mamdani said in a statement. “The attempt to use an explosive device and hurt others is not only criminal, it is reprehensible and the antithesis of who we are.”

Both Balat and Kayumi remain in custody as of Monday, March 9.

They each face several charges including: Attempted material support to a designated foreign terrorist organization (ISIS), use of a weapon of mass destruction, transportation of explosive materials, interstate transportation and receipt of explosive as well as unlawful possession of destructive devices
