Photographs of a Kappa Sigma fraternity member engaging in what appeared to be sexual activities with a woman on the roof of a campus building went viral after they were posted online over the weekend.
USC security workers said the couple triggered an alarm by opening the roof door and that other students called in to report the incident.
According to the Daily Trojan, the Panhellenic and Interfraternity councils have decided to create initiatives with women's groups and require at least 50 percent of each chapter's members to attend.
In the future, the councils also plan to use social media to educate new members about positive social images.
The man in the photos has been suspended from his fraternity until an investigation is completed. The woman is a student at a different local university.
