Champaign and University police are searching for a man who attempted to sexually assault a woman in her apartment complex at the 500 block of east Healey Street around 2:15 a.m. Sunday morning.

According to a news release, the 21-year-old woman reported the man came up behind her and grabbed her. The victim was in a hallway at the time of the attack, department spokeswoman Rene Dunn said Monday afternoon. The specific building address is not being released to protect the victim’s safety and identity, Dunn said.

He threatened bodily and sexual harm against the victim, who struggled and yelled for help. No weapon was indicated to police, Dunn said.

Witnesses nearby heard her and the suspect fled the building. Police had not located the suspect as of Monday afternoon.

The suspect is described as a Hispanic male, approximately 25 years old, weighing about 160 pounds and estimated to be a 5-foot-7 inch man. At the time of the attack, he was wearing a white T-shirt with red graffiti and blue jeans.

To avoid sexual assault, police suggest avoiding walking alone or in dark areas at night and being cautious in isolated spots such as laundry rooms, underground garages or parking lots. If confronted by an attacker, pay attention to physical characteristics if you can see the person and use your loudest voice to yell for help.
