COLUMBUS, Ohio (AP) -- A fraternity at Ohio State University is being suspended after a hazing allegation because of what fraternity officials describe as a pattern of unacceptable behavior spanning several years.

A letter from the general secretary of Beta Theta Pi says its trustees decided to close the Ohio State chapter partly because of "a lack of transparency" during the investigation of the hazing allegation. It also says members' conduct has violated the standards of the school and the organization.

The Columbus Dispatch reports the school and the fraternity have not released details about the allegation.

The suspension of its charter means the fraternity could return to campus if school and fraternity officials approve it.

The fraternity shut down its Ohio University chapter last year, citing alcohol violations.
