Swastikas were drawn last weekend on four dormitory doors at The New School, the private research university in Lower Manhattan.

University President David Van Zandt condemned the graffiti as “completely abhorrent and antithetical to our core values” in a news release.

At least one of the swastikas was drawn in black on the door of a dorm room shared by three Jewish students.

The New School was founded in 1919 and set up as the University in Exile in 1933 to serve scholars escaping from Nazi Germany, according to the The New School for Social Research website.

Zandt said the NYPD is investigating the matter.

Mayor Bill de Blasio called the graffiti “reprehensible” in a Twitter post.

“To the affected, we stand with you,” he wrote. “To the perpetrators, we have better than this.”

The election of Donald Trump as president has instigated a few incidents of hateful graffiti. Swastikas were painted on the windows of a vacant storefront in South Philadelphia after the election. The “T” in Trump’s name was converted into a swastika in that graffiti.
