PUEBLO, Colo. (AP) - State inspectors are forbidding a teen treatment center from putting its charges in effective solitary confinement.

The Pueblo Chieftain reports that the state found three violations at El Pueblo ... An Adolescent Treatment Community. It ordered the program to stop sending youths to so-called "reflection cottages."

Staff would reportedly push youth into the cottages and sometimes hold doors shut with their bodies to confine them there.

The state Department of Human Services found that some teens spent as much as two weeks in the cottages.

The investigation followed complaints by the American Civil Liberties Union of Colorado that the treatment program was violating juveniles' constitutional rights.
