Ariel Castro 'kept his WIFE chained up in the basement where he later locked his victims and whipped her with dog chains' Castro 'kicked Grimilda Figueroa in the stomach when she was pregnant' Alleged treatment foreshadows the crimes 'he inflicted on his captives' 2005 court filing claims she suffered two broken noses, a blood clot on the brain, shattered ribs and a knocked-out tooth at the hands of Castro Ariel Castro kept his former wife tied up in his basement and whipped her with dog chains, according to her former boyfriend, foreshadowing the horrific crimes he would later allegedly inflict on his three captives. Fernando Colon, who welcomed Castro's wife Nilda Figueroa into his home after she left her abusive husband, said that the man would viciously kick her in the stomach while she was pregnant. Castro similarly beat his kidnapped victims, Amanda Berry, Michelle Knight and Gina DeJesus, after he raped them and they fell pregnant, according to reports. He has been charged with three counts of rape and four counts of kidnapping after Berry managed to escape the Cleveland home on Monday and alerted authorities to their horrendous plight. 'Abuse': Ariel Castro, left, who has been arrested for allegedly imprisoning three missing girls for ten years, also locked his wife, Nilda Figueroa (right), in the basement and beat her, a former boyfriend has said Speaking to the New York Post, Colon recounted the treatment Figueroa, who passed away last year, allegedly suffered at the hands of her former husband. 'He kept her tied up in the basement,' he said. He used to whip her with dog chains. She wasn't allowed to go out... He pretty much kept her locked up in there. He added that Castro would push her down the stairs and kick her in an attempt to abort her babies. Even after she underwent brain surgery, Castro would hit her in the head, Colon said. Court records from 2005 claim that Figueroa suffered two broken noses, shattered ribs, a blood clot on the brain, a knocked-out tooth and two dislocated shoulders at the hands of her former husband. The documents, which emerged this week, also claim that Castro 'frequently abducts his daughters and keeps them from mother' and would frequently threaten to kill Figueroa. 'Former crimes': Ariel Castro was arrested in 1993 for domestic abuse but was not indicted Colon worked at the hospital where Figueroa was frequently sent for treatment for her injuries and, moved by what he saw, he invited her to live with him and his parents, he said. They went on to have a child, which infuriated Castro and he accused Colon of molesting his daughters. When the case ended up in court, Castro's son said it was lies, Colon said. The judge dropped the charges but Colon still served three years probation. Colon said that authorities once questioned whether he was responsible for the disappearances of the girls, but that he countered they should look at Castro instead. He told the Post that police never followed up on his suggestion. The 2005 filing, which lists Figueroa's injuries, asked the court to pass a protection order banning Castro from contacting his former wife or their children and from harassing them. She passed away from brain cancer in April last year.
