OBERLIN, Ohio (WKYC) --The student body of Oberlin college rallied Monday to send a clear message to whomever is responsible for racial tensions and graffiti on the campus --"We are United against you and your messages of hate."

Classes were cancelled Monday after an early morning incident where a student claimed to see a person wearing a Ku Klux Klan hood and robe.

That comes after a months of incidents -- at least 16 reported to police -- of racial, sexist and homophobic graffiti and flyers on campus.
