A female inmate who was housed at the Otter Creek Women's Prison in Kentucky has filed a lawsuit against the state of Hawaii and the company that operates the prison, alleging she was sexually assaulted by a guard while incarcerated.

Pania Kalama, 35, alleges in her Circuit Court lawsuit that the state and Corrections Corporation of America knew about improper behavior by corrections staff at Otter Creek, but took no actions to ensure the safety of inmates.

Kalama said she was sexually assaulted on June 13 by corrections officer Charlie Prater, according to the lawsuit. Last month, Prater, 54, was indicted in Kentucky on a charge of first-degree rape.

Hawaii corrections officials sent 165 women inmates to Otter Creek, a private prison operated by Corrections Corporation of America. State officials removed the inmates from the facility following allegations of sexual assaults of inmates by staff.

The lawsuit, which was filed by attorney Myles Breiner, seeks an undetermined amount in damages.
