We didn't know about kidnap victims, say Castro's brothers The brothers of the US man charged with kidnapping and raping three women - locking them in his home for a decade - say they had no idea what was happening. "If I knew that my brother was doing this ... I would call the cops because that ain't right," Pedro Castro, 54, told CNN. If I knew, I would have reported it - brother or no brother. Pedro and his brother Onil, 50, were arrested soon after their brother Ariel Castro, when the three women, and a daughter born to one of them while in captivity were discovered at Ariel's home in Cleveland, Ohio. Both brothers were later released, police saying there was no evidence against them. Ariel remains in custody. Onil Castro, left, Pedro Castro, center, and Ariel Castro, right. Ariel Castro was charged with four counts of kidnapping and three counts of rape. Pedro and Onil Castro, were later released without charge. Pedro and Onil said they feared they would never be free of the suspicion raised after police made their mug shots public. It's going to haunt me ... because people going to think, 'Yeah, Pedro got something to do with this'. Onil said: "The people out there that know me, they know that Onil Castro is not that person and has nothing to do with that, would never even think of something like that." The two brothers and their mother, 71, are in hiding, saying people have thrown rocks at their homes and sent them death threats over the internet, CNN reported. Ariel Castro, 52, , was arrested after one of the victims, Amanda Berry, 27, managed to call out to a neighbour, who rescued her and her daughter. Police found Gina DeJesus, 23, and Michelle Knight, 32, in the house.
