KNOXVILLE, Tenn. -

The Pi Kappa Alpha fraternity cannot operate for the next month on the campus of the University of Tennessee.

University officials say the fraternity's international office made the decision on Tuesday. The action comes after an ongoing UT police investigation.

The Knoxville Police Department says fraternity members used "alcohol enemas." That discovery was made in the early morning hours Saturday.

As Knoxville NBC affiliate WBIR learned (click here for original story), a hospitalized student sparked the investigation when hospital officials learned the 20-year-old had a blood alcohol level of more than .40.

The UT medical center says the hospitalized student has been released from the hospital as of Tuesday evening.

The fraternity's international office said in a press release that the student's actions are inexcusable, but their thoughts and prayers are with them and their families during this difficult time.
