SYRACUSE, N.Y. (AP) — Eighteen Syracuse University students face disciplinary charges after videos emerged showing fraternity members using racial slurs and simulating a sexual assault of a disabled person.

Department of Public Safety Chief Bobby Maldonado announced Sunday that investigators had filed complaints against the students. He said the investigation into the Theta Tau videos was continuing and others "may be implicated in the coming days." Syracuse.com reports that students could face suspensions of expulsions.

Syracuse University expelled the engineering fraternity shortly after the first video surfaced last week. Chancellor Kent Syverud on Sunday called the latest video clip of crude behavior at Theta Tau "appalling and disgusting."

Maldonado says the students were removed from class "out of an abundance of caution" and that alternative class and study arrangements are being made for them.
