The University of Tennessee has suspended a campus fraternity chapter until at least 2015 in an alleged alcohol enema incident.

The school announced Friday that the Pi Kappa Alpha house will be closed on Oct. 7 and that the campus chapter has notified the national fraternity that it is voluntarily surrendering its charter.

Knoxville Police said that one fraternity member was admitted to the hospital earlier this week with a dangerously high level of intoxication after receiving an alcohol enema. A dozen people were later cited for underage drinking.

Twenty-year-old Alexander P. Broughton has denied that that he received an alcohol enema, though police records dispute that claim. Broughton’s father has said his son has recovered and returned to classes.
