Two suspicious devices were found on Saturday outside Gracie Mansion, the official residence of New York City Mayor Zohran Mamdani.
Officers were on scene at the time for a scheduled demonstration near the residence, the NYPD told The Independent.
They were alerted around midday to the devices and took two “persons of interest” into custody, police said.
“No injuries or property damage have been reported at this time,” a department spokesperson added.
It is unclear if the mayor or first lady were present at the residence at the time of the threat.

The Independent has contacted the mayor’s office for comment.
Smoke started coming out of one of the devices, and the NYPD bomb squad is investigating, WABC reports.
Photos from the scene appear to show one of the devices, a round object wrapped in metallic tape.
The arrests took place during an anti-Islam protest led by conservative influencer Jake Lang.
There, Lang and his far-right supporters met a contingent of counterprotesters, and the groups traded blows, while a far-right protester reportedly pepper-sprayed members of the opposing group.

“Four people got hit, at least,” an eyewitness told amNewYork.
Lang himself walked a goat through the crowd, and police later helped him exit the area.
At least six people total were arrested at the demonstration, including one person for disorderly conduct and another for using pepper spray, police sources told ABC News.

Earlier this month, Lang, a January 6 rioter, was charged with making threatening statements about a police officer who was present at a fifth-anniversary event commemorating the attack on the Capitol.
The provocateur was also arrested last month for vandalizing an ice sculpture at the Minnesota State Capitol protesting the Trump administration’s immigration agenda.
The previous month, Lang was in Minneapolis, where he led a “crusader march” demonizing Muslims. He also used his visit to praise immigration agents, who had just fatally shot protester Renee Good in the city.
During a January 17 demonstration there, Lang was vastly overwhelmed by counter-protesters who chased him from the city’s federal courthouse and targeted him with water balloons amid sub-freezing temperatures.
President Trump pardoned Lang along with most others who faced prosecution after the January 6 riot.
