An unidentified freshman woman was assaulted near Kiewit Computation Center in the early morning of May 30.
About 3:15 a.m., the woman was grabbed from behind by her hair by a man who appeared to be drunk, according to a Safety and Security press release.
The victim spun around and yelled at her assailant, causing him to flee toward Kiewit, the release states.
The victim described her assailant as a college-aged male, six foot, 200 pounds and having dark, medium-length hair.
Hanover Police Chief Nick Giaccone said the police department could not release any details regarding the assault.
But he said police cannot make a complete investigation because they do not have enough information.
"We have very little to go on," Giaccone said. "We're at a dead end."
