Investigators are looking into reports that boys were beaten by a former staff member and forced to wear leg shackles and handcuffs for minor infractions of ranch rules.
The Albuquerque Journal reports in Saturday's editions that the program is run from the Tierra Blanca Ranch north of Las Cruces near Hillsboro. It caters to parents who can't deal with their children's drug use or other behaviors.
State police and an official with the state child welfare agency confirmed the investigation.
A statement from ranch owner Scott Chandler said he is "proud of its success in serving families and their at-risk children over the years."
