Investigation established probable cause to believe unidentified persons committed the offense of Cruelty and Maltreatment when they flex-cuffed the detainees in positions for long periods of time causing extended amounts of stress on the joints of the detainees, but showed no other evidence of abuse. Some detainees complained of beatings and other abuse. Soldier/officer states that detainee's eyes are taped shut as a measure to keep them from knowing the layout of the facility and that they are put in stress positions for up to one hour.
