The NYPD's Hate Crimes Unit is investigating after anti-Semitic graffiti was reportedly found at Columbia University's Teachers College.
Professor Elizabeth Midlarsky told the Daily News two swastikas and an anti-Semitic slur were spray painted on a wall outside her office.
Midlarsky is a Jewish Holocaust scholar.
She says she was the victim of a similar incident in 2007.
Columbia has denounced the graffiti, saying it condemns any expression of hatred.
