BOISE, Idaho (AP) — The Idaho State Police has launched an investigation into staffing levels at the state's largest private prison after state officials said they found discrepancies in the prison's monthly reports. The Idaho Correctional Center is run by the Nashville, Tenn.-based Corrections Corporation of America under a contract with the state. The contract details the way CCA must run the prison.

Correction Director Brent Reinke told the Idaho Board of Correction Tuesday morning he asked the state police to investigate because the department found "potential anomalies" during an audit. The department didn't begin taking a deeper look until recently, around the time The Associated Press filed public records requests for shift logs at the prison. CCA spokesman Steve Owen didn't immediately respond to a request for comment.
