Students from the University of Massachusetts Amherst led protests on their campus this weekend in response to allegations of sexual assault made against fraternity Theta Chi. A post on the anonymous social media app Yik Yak alleged a first-year student at the university had been drugged and assaulted by a member of the fraternity at a Theta Chi party on Saturday night, Sept. 18. The following Sunday, Sept. 19, around 300 people gathered outside the fraternity house to protest the member’s involvement in the sexual assault allegations.
