BOISE, Idaho (AP) — The American Civil Liberties Union has reached a settlement with the Idaho Department of Correction in a lawsuit over violence at a privately run prison near Boise.

The ACLU filed the lawsuit against Corrections Corporation of America and the state earlier this year, saying the Idaho Correctional Center is so violent that inmates refer to it as "gladiator school" and that guards deliberately expose prisoners to brutal beatings from other inmates.

The ACLU's lawsuit against CCA still stands.

CCA has said the prison meets the highest professional standards.

Under the agreement, the Idaho Department of Correction agrees to oversee compliance with any orders a federal judge makes against CCA in connection with the lawsuit.
