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.
