LINCOLN, Neb. (AP) — The University of Nebraska-Lincoln has suspended its Alpha Tau Omega fraternity chapter, citing a culture within the fraternity of alcohol use.

The fraternity has been affiliated with UNL since 1897. Following Wednesday’s announcement, it will no longer be affiliated with the university and its chapter house will not be recognized as a university-approved housing unit. Freshmen will not be allowed to live in the chapter house.

The suspension is in effect until May 2017. That can be shortened by up to one year if the organization takes action to address the university’s concerns.

The Alpha Tau Omega national office, based in Indianapolis, said in a statement Wednesday that the Gamma Theta chapter agreed to the sanctions and that it is expelling fraternity members whose actions led to the suspension.
