Pi Beta Phi is under investigation by the UA for alcohol infractions.
Samantha Kenter, president of the sorority, informed sorority members of the investigation in an e-mail sent to the Pi Beta Phi Listserv.
According to the statement, effective immediately, Pi Beta Phi will not be participating in any registered or non-registered events, including formal and informal events and fraternity parties, until further notice.
Members were asked by Kenter to block all Facebook accounts and to remove all inappropriate pictures from that Web site.
""I promise to keep everyone posted with information as soon as I find out myself,"" Kenter told her sorority sisters in the e-mail. ""Please remember that everything you do effects our entire house so do not take this message lightly.""
Members at the house had no comment and said they were waiting for word from their president, who was meeting with the dean of students. Kenter could not be reached for comment by press time.
