57 swastikas were found at a children's playground in Gravesend Park, Brooklyn.
They were painted on playground slides and on the wall of a handball court in red, yellow and blue paint with other antisemitic vandalism.
The NYPD says this is being investigated as a hate crime.
It's described as aggravated harassment and police responded just before 11 a.m. to find all this hateful graffiti. No arrests have been made.
It's the second day someone targeted this park.
As of the afternoon, it's no longer a crime scene, just a cleanup scene as the Parks Department crew members use paint thinner to get it off and light grey paint to cover it up.
NYC Mayor Zohran Mamdani called the display of antisemitism 'sickening' in a post on social media.
"I am sickened by this antisemitic vandalism in Borough Park. Antisemitism has no place in our city, and I stand shoulder to shoulder with the Jewish New Yorkers who were targeted. My administration is working closely with the NYPD's Hate Crimes Task Force as well as our Parks Department, and those responsible will be investigated and held accountable," Mamdani said.
Other elected leaders and the ADL are also condemning this incident.
The local community board says it's the second time it's happened here in two days and the culprit needs to be caught and brought to justice.
Last Friday, City Council speaker released a five-point plan to combat antisemitism.
Speaker Julie Menin reacted to the incident on social media.
