(CBS) - Police arrested a 42-year-old Montana man Tuesday evening for allegedly "waterboarding" four young children, two of whom were his own, CBS affiliate KXLF reports.
William Province was arrested at the Helena airport where he returned from a trip to Alaska, the station reports.
According to an affidavit, the boys - ages 9 and up - were subjected to a water-torture technique that simulates the effects of drowning at Province's home. Province reportedly meant it as a "learning experience."
Province was in the process of waterboarding the fourth child when his girlfriend walked in and tried to stop him, according to the affidavit. He then allegedly held her arm behind her back so tight that she received a broken wrist and two broken fingers, the station reports.
Province was charged with multiple assault charges and one count of intimidation. He is held in jail on $200,000 bond and his arraignment will be scheduled in January.
