Indiana University has suspended a fraternity for allegedly performing a hazing ceremony that involved "sexual misconduct," the university said late Wednesday.
Alpha Tau Omega would be banned from hosting social events and sponsoring new members while the investigation was underway, according to IU spokesman Mark Land.

The university has not been any more specific other than to say the frat is being investigated on "allegations of hazing activities which perpetuate sexual misconduct."
Responding to comments on Twitter, IU's Bloomington campus said: "We do not think this is humorous at all. We are taking this matter very seriously."
The chapter's president was informed late Wednesday, according to spokesman Land.
“Alpha Tau Omega National Fraternity has suspended all operations of the Delta Alpha chapter at Indiana University as we begin our investigation," Alpha Tau Omega National Fraternity CEO Wynn Smiley said in a statement to NBC News. "We are working with the University. The video is highly offensive and is antithetical to the values of Alpha Tau Omega. If confirmed, swift disciplinary action will be taken. The men who were a part of such a vulgar incident do not represent the fraternity and damage the fraternity’s name for thousands of ATO undergraduates and alumni across the country.”
It is not the first time ATO's Indiana chapter have run into trouble with college authorities.
Two-thirds of its members were kicked out in 2010 following an investigation into hazing and alcohol violations, according to The Associated Press.
