Indiana University suspended a fraternity on Wednesday in the wake of hazing allegations, which appeared to include a video purporting to show a student being forced to perform oral sex on a woman. It’s unclear if either person in the video is consenting. The university tweeted Alpha Tau Omega had been suspended immediately, pending an investigation into “allegations of hazing activities which perpetuate sexual misconduct.” The 29-second video surfaced online through an account called “ATO Video.” The video purports to show a crowd of men both shirtless and clothed looking on at two women, Gawker reports. One male appeared to be performing oral sex on one of the women.
