The U.S. Education Department says it's closing a four-year federal investigation into Ohio State University's handling of sexual abuse allegations on campus.

In the announcement Thursday, the government agency also noted that the university's recent investigation of a "sexualized culture" within the school marching band set important expectations for a culture of prevention.

The university fired band director Jonathan Waters on July 24 after a two-month university investigation concluded he turned a blind eye to the band culture.

Waters' supporters say he's been made a scapegoat.

As part of the agreement, Ohio State agreed to revise certain policies and review the handling of sexual violence and harassment complaints since the 2011-12 school year.

The government says the investigation was proactive and not related to any specific complaints.
