(NBC NEWS) The three women held in a Cleveland house for a decade have told investigators of rapes, pregnancies and miscarriages during their captivity, police sources told NBC News on Wednesday. The police chief said they had been bound with chains and ropes.

Police were seeking corroboration of the women’s accounts where possible, the sources said. Police planned to make some details public later in the day, the sources said, including how one of the women managed to break free and scream for help Monday night before a neighbor came to her rescue.

Another woman, Gina DeJesus, gave the first details of her capture, the sources said: She told investigators she was abducted on her way home from school one day in 2004 when a man pulled up in a van and casually said, “You need a ride? I’ll give you a ride home from school.”
