The News & Observer reported on October 28, 2026 that NC State University and university police were separately investigating alleged hazing involving Sigma Nu's Beta Tau chapter. The university placed the chapter on interim suspension, and Sigma Nu's national organization also suspended chapter activities pending investigation. Neither the university nor police provided further details about the investigations. The article identifies no individual accused members and reports no arrests or criminal charges. Separately, university police received an anonymous report earlier in October alleging hazing using date rape drugs at an unspecified fraternity. The cited report does not establish that this anonymous allegation concerned Sigma Nu, and it is not attributed to Sigma Nu here. The exact incident date is not reported; October 28 is the article publication date. Allegations remain unproven.
