State authorities are investigating an allegation by an adult female that she was raped by someone who appeared to be a police officer or security guard, the Oak Ridge Police Department said Wednesday afternoon.

The woman was interviewed by Oak Ridge police officers on Tuesday. The Police Department then contacted the Anderson County District Attorney General’s Office, which notified the Tennessee Bureau of Investigation of the allegation, the ORPD said.

TBI Public Information Officer Josh DeVine confirmed that the bureau is investigating the allegation, but he said he can’t discuss any details, including when and where the alleged rape is alleged to have occurred or whether it might involve a security guard or police officer.

“It’s very preliminary at this point,” DeVine said.

More information will be add as it becomes available.
