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. ATO's national office did not immediately respond to request for comment when contacted by NBC News.
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.
