A 19-year-old female UW-Madison student reported being sexually assaulted in Ogg Hall early Friday morning, according to University of Wisconsin police.

According to UWPD, the female student “encountered the male while in a stairwell and accompanied him to a dorm room where she reports being sexually assaulted.”

UWPD described the suspect as a white male, about 18-20 years of age, between 5’7” and 5’9,” with “short, curly dirty-blond color hair,” and no facial hair.

Lt. Peter Ystenes said Sunday the case is still under investigation.

“It’s a little bit sketchy what happened,” Ystenes said. “We’re working with the victim and helping support her and making sure we get the story right before we move too fast. We’re still gathering information and she’s helping us out.”

He said police have acquired all video of the building from the hours around the assault and are trying to assess what evidence, if any, can be used.

Due to the vagueness of the case, UW housing and the dean of students joined police to ask residents if they knew further details.

University Housing sent an “important notice” e-mail to Ogg residents Friday afternoon, telling them to contact police with more information, and reminding them to be aware of their own safety.

Police are still asking anyone with information regarding the incident or the possible identity of the suspect to contact UWPD at 608-264-2677. More information on the case should be released today, police said.
