University Police Chief Derek Poarch said Wednesday's assault involved a man who approached a 21-year-old female student in a University parking lot, where she was monitoring access for a special event.
The two spoke briefly in Spanish, and the man then touched the student's chest and pelvic area, reports state.
University police Lt. Archie Daniel said Thursday that police have received several Crime Stoppers calls about the suspect, who is described as a Hispanic man, about 5 feet 5 inches tall, about 30 years old and of medium build, with a slight mustache and poor teeth.
"We know a lot more than we did (Wednesday night)," Daniel said. "We hope to make an arrest."
But Student Body President-elect Jen Daum said she worries that assaults like Wednesday's could happen more frequently if the proposed parking plan is implemented.
"My real concern is that this (assault) is just the beginning of what will happen if the current night parking proposal is accepted," she said.
The proposal, which was approved Tuesday by the chancellor and vice chancellors, would charge students $122 for a permit and limit students without a permit to two specific lots. The UNC Board of Trustees will vote March 28 on the plan.
Students who do not purchase a permit would have the option to park for free at the Bowles Drive Parking Lot on South Campus and the Bell Tower Parking Lot. Officials will increase bus service to transport students from the lots to main campus, but the busing would end at midnight -- a fact that worries some students.
Kindl Shinn, co-chairwoman of Advocates for Sexual Assault Prevention, also said she thinks the safety of students walking on campus or standing in campus parking lots is a main concern.
