Two more fraternities at NC State are being investigated for hazing allegations.
University officials say Delta Sigma Phi and Sigma Alpha Epsilon were involved in a late night scavenger hunt that may have violated school policies and codes of conduct.
At East Carolina University, ECU Greek life officials say they haven't had a hazing problem for several years. They say they teach students the law, as well as the university's zero tolerance policy.
School officials say Greek life members at ECU must attend occasional hazing seminars to better understand what it means and why it's illegal.
