Seven youths aged 11 to 16 were sent to house arrest for allegedly turning an 11-year-old boy into their sex slave for the past year during which they repeatedly sodomized and sexually assaulted him. Dep.-Cmdr. Amichai Ashad, chief of police in the city of Lod where the suspects and the victim live, told Channel 2 television Tuesday that the attacks included extreme violence and forced sexual acts. He added that the boyâ€™s parents were apparently unaware of the assaults. The alleged crimes were discovered when the victim confided in a 15-year-old friend who went to the police with the information. Ashad said that the boy, apparently frightened by the policeâ€™s involvement, disappeared for a few days. Once he was found, he agreed to speak to investigators. Police said they would most probably make additional arrests.
