An investigation into allegations that Iraqi detainees were punched in the head and stomach in the back of a U.S. Army vehicle by numerous soldiers after being taken from their house in the middle of the night. The investigation was initiated after a soldier assigned to C Co., 5/20th Infantry, SBCT, Q-West, Iraq sent an email suggesting that detainees had been assaulted in the rear of a Stryker vehicle. The investigation established "insufficient evidence to prove or disprove" the allegation of abuse.
