Indiana University says it has suspended the local chapter of the Alpha Tau Omega fraternity while it investigates a sexually explicit video purportedly showing the hazing of a pledge.

School spokesman Mark Land said in a statement Thursday that he can't "confirm the contents" of the video but that the school immediately suspended the fraternity's local chapter Wednesday night "given the seriousness of the allegations and the purported content of the video."

Alpha Tau Omega's national CEO Wynn Smiley says in a statement that the video "is highly offensive" and "vulgar" and that if confirmed "swift disciplinary action will be taken" against those involved.
