The University of Minnesota's Delta Upsilon fraternity chapter has been temporarily suspended amid an investigation into "inappropriate chapter culture, behavior and operations."
The suspension was imposed by the international fraternity, which said the chapter would not be allowed to carry out activities, including social events, while it is in place.
The Minnesota Daily reports that the fraternity has been the subject of several sexual assault allegations in the past few years, which resulted in at least one student expulsion and one suspension by the university, and the expulsion of two other chapter members by the international fraternity.
But the Daily says that it was contacted more recently by a chapter member suggesting there are still problems within the frat house.
CityPages reports two new assault violations were filed with the school earlier this month, both allegedly happening at Delta Upsilon.
Don Powell, the frat's alumni counselor, told the magazine that the chapter member who contacted the international fraternity "has all of the sudden gotten some unusual morality." He added that the chapter member "thought it was immoral not to send the email to international."
According to WCCO, current members of the fraternity feel they're paying for the transgressions of former members who were expelled or suspended for their misconduct.
Sexual assault involving fraternities has come increasingly under the spotlight. A CNN column in 2013 reported that at least three studies – including one by the University of Minnesota – have found that fraternity members are three times more likely to commit rape than other men.
