The victim, a female undergraduate, described her attacker to police as a six-foot tall male with crew-cut hair.

The term "sexual assault" encompasses a variety of crimes, ranging in seriousness from indecent assault to rape. Because the victim filed a police report on condition of anonymity, however, Riley declined to comment on the nature of the assault.

"The victim is extremely publicity-adverse," Riley said, "and so we are willing to go overboard to protect her. We are seriously constrained in the information we can give out."

The department has not put into place any additional security measures in response to the assault, Riley said.

"There have been other instances when we have had reports of break-ins and have had to increase patrols," Riley said. "At this time, however, I haven't assigned any additional officers. I don't view this as a serial entry.

While Riley said students should not be overly concerned about this particular case, he still urged them to pay closer attention to personal safety.

Police officers do believe the dorm room where the attack occurred was unlocked, Riley said.
