Benedictine University is now banning all alcohol at apartments and dorms on its west suburban Lisle campus.
It follows claims by two young women that they were sexually assaulted in a dormitory.
The ban also includes the campus residences of students age 21 and over.
School officials say if any student is caught with alcohol on campus, they could lose housing privileges.
The move comes less than two weeks after the two women said they were assaulted after leaving a party where alcohol was served.
Charges aren’t being pursued in the case. Police say there is not enough evidence.
