Ugh. In a stark reminder that one in five American women experience sexual assault, Portland Police are investigating the sexual assault on a Portland State University student.

From their announcement:

On Tuesday December 20, 2011, at 3:20 p.m., Portland Police officers assigned to Central Precinct responded to the report of a female screaming in the lower area of the Portland State University Academic and Student Recreation Center. As officers were enroute, Portland State University Public Safety advised that they were enroute to the call also.

Officers learned that an unidentified male suspect followed the 27-year-old female victim into the restroom, exposed himself and sexually assaulted the woman by touching her in a sexual manner. The suspect then fled the area on foot. The victim is a student at Portland State.

The suspect is described as an unknown race male, lighter skinned, described as in his 30s, approximately 5'08" to 5'09" tall, medium build.

Good on the victim for reporting the crime. Hopefully they can catch the guy. Police have gathered surveillance video of the suspect—it's a little hard to really see what he looks like from the footage, but keep an eye out.
