Yale University has banned a social fraternity from campus for two years over a violation of the school's sexual misconduct policy.

The university's chapter of Sigma Alpha Epsilon is being punished for what the fraternity describes as a presentation made at a February 2014 initiation ceremony.

Dean Jonathan Holloway says in a message to students that the fraternity has taken steps to respond to the violation and "improve the general climate that led to it."

Holloway also shared a letter from SAE fraternity brothers who apologized for the harm they caused but did not provide details of the offense.

The issue of sexual abuse on U.S. campuses exploded after a recent Rolling Stone article detailed an incident at the University of Virginia. The article was later retracted.
