Ohio University issued a cease and desist order Wednesday for three sorority chapters and one professional fraternity after receiving hazing allegations.

The three sororities — Delta Zeta, Chi Omega and Pi Beta Phi — are all members of the Women’s Panhellenic Association. Phi Chi Theta, a professional fraternity at OU, was also issued a cease and desist order.

OU does not have reason to believe there is a systemic culture issue within the Women’s Panhellenic Association organizations or professional organizations, according to a university press release.
