NEW YORK (AP) — The president of Columbia University's Teachers College sent an e-mail to students and faculty members deploring the discovery of a hangman's noose on the office door of a black professor.

Police are investigating the incident as a hate crime, and Columbia planned a town hall meeting Wednesday afternoon for faculty and students to address the incident.

The university did not immediately say which professor was targeted, but she was identified in the local media as Madonna Constantine, a professor of psychology and education and author of a book entitled "Addressing Racism: Facilitating Cultural Competence in Mental Health and Educational Settings."

Students said Constantine, who is black, teaches a class on racial justice.

Calls to the publicist for Teachers College and Constantine's office were not immediately returned.

"You would think, Columbia being such a diverse campus and New York being such a diverse city, it shouldn't happen here," said student Mikayla Graham.

In the message to the college's 5,000 students and 150 faculty members explaining why police were on campus Tuesday, college president Susan H. Fuhrman said: "The Teachers College community and I deplore this hateful act, which violates every Teachers College and societal norm."

Teachers College, founded in 1887, describes itself as the nation's oldest and largest graduate school of education.

According to its Web page, the college brought black teachers from the South to New York for training in the early part of the 20th century, when schools in the South were segregated.

The college has a diverse student body, including students from nearly 80 countries. The racial breakdown is 12 percent black, 11 percent Asian American and 7 percent Hispanic.

The hangman's noose was discovered Tuesday morning, in an echo of other recent incidents involving the symbol reviled by many for its association with lynchings in the Old South.

Last year in Jena, La., three white students hung nooses from a big oak tree outside Jena High School. They were suspended but not prosecuted.

Racial tensions rose and a white student was beaten unconscious three months later. Recently, thousands of people protested the arrests of six black students in the incident.

Columbia has been the site of other campus turmoil, most recently last month when Iranian President Mahmoud Ahmadinejad was invited to speak, prompting protests by groups angry over his statements questioning the existence of the Holocaust.

Last fall, Columbia was in the spotlight when a group of students stormed a stage to silence a speech by Jim Gilchrist, the founder of a group opposed to illegal immigration.
