A major fraternity at the University of Missouri in Columbia is being shut down.

Delta Sigma Phi officials say they’ve closed indefinitely, following an investigation into a “Pattern of behavior that goes against the values of the fraternity.”

According to a release, the campus police department are now investigating.

The closure means the fraternity will lose its recognition from the college for a minimum of three years, and members are banned from participating in programs like homecoming.

It’s not the first fraternity closed in this year; Sigma Chi was also suspended by the University for similar allegations.
