All Greek social functions at San Diego State University have been indefinitely suspended and all members of campus fraternities and sororities will undergo sexual assault prevention training, the university's Greek leadership groups announced Tuesday.

The decision came after several fraternity members interrupted a "Take Back the Night" march -- in which survivors and advocates raise awareness about sexual violence -- by yelling obscenities, waving sex toys, and throwing eggs at marchers, the San Diego Union Tribune reported. With the party ban, San Diego State joins a growing number of colleges that have suspended Greek social functions this semester, including Clemson University, Emory University, Johns Hopkins University, the Massachusetts Institute of Technology, the University of Virginia and West Virginia University.
