A Clemson University student who claims she was sexually assaulted at an off-campus fraternity party was arrested for lying about the attack, authorities in South Carolina said.

Sarah Katherine Campbell, 18, of Herndon, Virginia, was booked Wednesday on one charge of filing a false police report in connection with the alleged assault at the Delta Chi frat house in Seneca on Jan. 27, according to the Oconee County Sheriff’s Office.

Her arrest came after investigators found evidence suggesting that the sexual encounter between Campbell and a man at the fraternity house was consensual and that Campbell “had not been truthful in the information” she gave to police, according to Jimmy Watt, public information officer for the sheriff’s office.

Reached by the Anderson Independent Mail on Thursday, Campbell insisted she’s not at fault and reiterated her original claim that she was assaulted at the party.

“I’m a victim of sexual assault,” Campbell told the newspaper. “This story is being blown out of proportion, and that’s all I can say.”

Campell was booked into the Oconee County Detention Center and later released on $5,000 bond, Watt told the newspaper.

All fraternity activities were suspended by Clemson’s Interfraternity Council one day after the alleged assault. The governing body for the university’s 20 fraternities said at the time that the step was being taken to ensure that members were held to a “higher standard,” according to a statement posted on its website.

“Therefore, we are suspending all social events at fraternity houses effective immediately,” the statement continued. “This suspension will be effective until necessary measures are taken.”

In a letter to its members late Thursday, IFC officials referenced the Jan. 27 incident that led to the suspension and announced new procedures at Greek events, including the requirement of university IDs for entrance at all social functions, mandatory guest lists and wristbands, as well as a minimum of three security guards at all events.

“We believe that the procedures established will provide a safer environment for guests and members to socialize,” IFC president Landon Flowers wrote in a statement obtained by The Post. “We recognize that these procedures call for a culture change, and we look forward to your support in making that change.”

Messages seeking additional comment from Clemson officials were not immediately returned Friday.

Campbell, according to Clemson’s student directory, is majoring in political science. She did not return a message from The Post seeking comment.
