A fraternity has been expelled from Syracuse University after a video showed members mocking the disabled. Video from CNN shows members of the Theta Tau fraternity miming the sexual assault of a disabled person. The Washington Post reports that fraternity members can be heard describing a young man in a wheeled office chair as “brain dead.”

“He’s drooling out of his mouth because he’s retarded in a wheelchair,” a fraternity member says in the video, before three people surround the person in the chair and appear to mimic forcing him to perform oral sex. Others can be seen watching.

“They leave the helmet on for protection, but they don’t protect themselves,” the fraternity member says.

The video was first posted on a secret Facebook page, according to CNN, and later obtained by the Syracuse student newspaper The Daily Orange.
