Penn State University has suspended the Sigma Alpha Mu fraternity for two years for violating new, tighter alcohol rules during Parents' Weekend.

The new rules were imposed after the February death of a student at a pledge acceptance party hosted by another fraternity, Beta Theta Pi, which is permanently banned from campus.

University President Eric Barron says nine of the university's 82 fraternities and sororities violated at least one of the new rules, and Sigma Alpha Mu violated nearly all of them.

Barron says drinking was excessive, not restricted to wine and beer and that no third-party licensed server was used. Underage drinkers and parents were seen visibly intoxicated on April 1.

The fraternity hasn't commented. The school's Intrafraternity Council says the suspension was a "university decision."
