a call from bilash's wife confirms what we fear. bilash has been arrested. this cell phone video shot in the hotel room where he was apparently taken into custody, showing blood on the bathroom floor. >> he said that his life is in danger. >> in the weeks that followed, his wife confirms he's being held in another city on house arrest and charged with inciting ethnic hatred. >> i really think that china is standing behind his arrest because china really don't want to know about these concentration camps. >> she and their children are left to fend for themselves >> it feels like i am sitting in a small boat with my two children and in the middle of the huge ocean. i have to help him. i have to protect my children's father. >> now that our connection with bilash is severed, we head toward china. we drive to the border town of khorgos, where we're told many people leaving xinjiang cross over. to get there, we have to pass through gates and security checkpoints. all right, we are going through security right now to head to the direction of china. a lot of camera
