Police swarm NYC street Sunday amid IED probe near Gracie Mansion
The NYPD has cordoned off a tony Manhattan block near the mayor's residence amid a continuing probe into a potential terror plot involving improvised, ISIS-style bombs.
"Due to ongoing police activity, please avoid the area of East End Avenue between 81st Street and 82nd Street in Manhattan," the NYPD wrote on X on Sunday.
According to two NYPD sources, the activity is connected to the investigation into two devices that were thrown during dueling protests outside Gracie Mansion.

The activity follows hours after New York City officials confirmed that a device ignited and thrown during protests near Gracie Mansion on Saturday was an improvised explosive device (IED) capable of causing "serious injury or death."
The devices thrown near Gracie Mansion were allegedly charged with TATP (triacetone triperoxide), retired NYPD inspector Fox News contributor Paul Mauro told Fox News Digital, citing multiple sources.
