Two students were sexually assaulted over the weekend, one in Coronado Residence Hall and the other at a fraternity house.
Also, two students ÷ boyfriend and girlfriend ÷ were assaulted at another fraternity house.
The University of Arizona Police Department kept news of last weekend's string of incidents quiet as the cases are still in the initial phase of investigation.
The 18-year-old student in Coronado Residence Hall told officers Sunday afternoon that between the hours of 12:30 a.m. and 2:30 a.m., another student whom she knew sexually assaulted her inside her dorm room, said Cmdr. Kevin Haywood, UAPD spokesman.
