(Newser) – University of Illinois at Chicago freshman Mohammad Hossain, 19, is a student leader and athlete; he's also sitting in Cook County lockup on felony sex assault charges after what he says was a reenactment of a scene from Fifty Shades of Grey, reports the Chicago Tribune. The alleged Saturday night rendezvous was with a fellow freshman with whom he'd previously been intimate but was not dating. Prosecutors say that after asking her to undress in his dorm room, he proceeded to tie her hands above her head to a bed with a belt, bind her legs with another belt, stuff her mouth with a tie, cover her eyes with a knit cap, and strike her repeatedly with another belt—even after the woman said "no," "stop," and "you're hurting me," according to the police report, via DNAInfo. The report further states that the woman tried to escape several times, but that Hossain held her down and sexually assaulted her.

Hossain is a triathlete, student ambassador to the alumni association, and member of multiple UIC leadership programs. "How can someone involved in all that let a movie persuade him to do something like this?" asked the judge, who yesterday set Hossain's bail at $500,000. "He would say that it was consensual," replied his lawyer. The woman called university police the night of the incident, and Hossain admitted "doing something wrong." "It makes people think that this is kind of a healthy intimacy that they should try to engage in in order to spice up their relationship, but really it's just violence," a rep with the National Center on Sexual Exploitation tells ABC7. (See why the movie itself isn't impressing the critics.)
