Three children were allegedly raped and sexually tortured for several years by their parents and uncles in a dingy apartment crammed with toys and pornography.

The victims were two sisters, ages 13 and 14, and an 8-year-old boy, police said. The girls had been removed from the Brooklyn apartment by social workers, but returned by a judge over the workers' objections.Four men and a woman were arrested Wednesday. Detectives said there may have been more victims, and more arrests were expected, Chief of Detectives William Allee said.
