A Kansas University student reported she was knocked unconscious and raped by a man inside her dorm room Sunday night, campus police said.

The victim was grabbed and pushed against the wall when she entered her room at Oliver Hall, 1815 Naismith Drive, a statement from the KU Public Safety Office said. When she woke up 45 minutes later, the woman told officers she had been sexually assaulted.

Capt. Schuyler Bailey, KU police spokesman, said the victim left her room unlocked while she went to eat dinner with friends. She was attacked when she returned to her room around 6 p.m. Sunday.

“You have to lock your doors, whether you’re going across the hall, to the restroom, down to the dining facility, wherever,” Bailey said.

Officers are looking for the suspect, described as a white man with brown hair who stands 6 feet tall and weighs 170 pounds.

Anyone with information about the burglary and rape is asked to call the KU Public Safety Office at 864-5900 or KU Crimestoppers at 864-8888.

Campus police are urging students to call if they see someone who looks out of place at their residence hall or if they fall victim to a crime.

Bailey said the incident is not connected to a string of rapes in Lawrence and Manhattan over the last several years.
