VIDEO - Shocking discovery in West Bank: A Palestinian man imprisoned his two mentally ill children for more than 20 years in a dungeon he dug under his house because he was ashamed of them, Palestinian police said on Tuesday. Video courtesy of infolive.tv Police officers found the brother and his sister, in their 30s, in an unlit and unventilated dungeon during a raid against arms and drug dealers in the West Bank village of Beit Awa. The father told police he has imprisoned his children because he did not want people to laugh at him for bringing "abnormal children to this world." Police said the father had been arrested and the children were sent to a psychiatric hospital. The children's mother died years ago and their father remarried. He has two children from his second marriage. Police declined to give his name or other details. Several similar cases have been reported across the world in the past. In one such case, revealed earlier this year, a 73-year-old Austrian man was arrested on suspicion of imprisoning his daughter for 24 years and raping her repeatedly.
