A Queens schoolyard has been defaced with dozens of scrawled swastikas and anti-Semitic messages including “Hail Hitler” [sic] and “No Jews Allowed.”

The images, posted to Twitter by City Councilwoman Karen Koslowitz, show the hateful messages etched in chalk in the yard of PS 139 on 63rd Drive between Wetherole and Booth streets in Rego Park.

“I am horrified, disgusted, and nauseated, to say the least, of what I have witnessed today,” Koslowitz, who represents the area, said Friday.

The NYPD said its Hate Crimes Task Force is investigating.

But as of Saturday night, no arrests had been made.
