NYPD Commissioner Jessica Tisch and Mayor Zohran Mamdani provided an update Monday on the chaotic weekend of protests that culminated with an explosive being thrown near Gracie Mansion.

The incident occurred during a rally called “Stop the Islamic Takeover of New York City” and a nearby counter protest named “Run the Nazis Out of New York City — Stand Against Hate.”

Investigators say an 18-year-old counter-protester lit and tossed the explosive device toward the area. They say that same person later received a second device from another man and lit it, but dropped it before it ignited.

A total of six suspects were ultimately arrested. Later that day, police say a suspicious device was also found inside a parked car near the scene.

Tisch stated during Monday’s press conference that “this is being investigated as an act of ISIS-inspired terrorism.”

“Devices like these have the potential to cause devastating harm,” she explained. “We were fortunate that the devices used this weekend did not cause the kind of harm that they were certainly capable of causing.”

Mamdani also spoke, thanking the officers who apprehended the suspects and protected the public.

“I want to commend the officers who were on site, they faced a chaotic situation that very quickly could have become far more dangerous,” Mamdani said. “New York City will never tolerate violence, whether from protests or counter protests.”
