According to a news article (link below), Purdue is sanctioning the Alpha Tau Omega chapter for a scavenger hunt. The article also mentions Purdue's sanctions against a co-op house for alcohol violations.
I'm not happy about alcohol violations, of course, but I am pleased to see that the university -- and the news report -- aren't ignoring violations by non-Greek organizations.
