A 19-year-old University at Buffalo student who reported she was attacked on the university's North Campus early Monday has told investigators the incident never happened, the university announced Thursday.

The woman initially told police the attack involving two male assailants happened at about 2:30 a.m. in the area of Core Road near the Ellicott Complex's Millard Fillmore Academic Center. At first, police said they were investigating the report of a sexual assault. They later said it was the report of "an attempted assault, possibly an attempted sexual abuse."

Police investigated her claim and were "unable to find evidence" to support it. The woman then admitted to making the false claim, according to police.

“This incident created an atmosphere of concern on campus, and we think it is important for everybody at UB to know that we have determined that the alleged crime never took place,” University Police Chief Gerald Schoenle said in a written statement.
