As far as we know, Razwan has had no contact with Atiya himself. He's never received any letters or photographs of Atiya, so there's no way that he knows how she is.
We've been to see him a few times. He maintains the facade she's in Iran but there's no evidence to support that, so we're very sceptical. It's only him that holds the information.
We're working with a range of international agencies in order to find out who may be harbouring her, but it presents its challenges and problems and hopefully this is now the time to tug at heart-strings and generate information from the public.
We haven't got any evidence to know she's even alive. This is the only way he can exert control. He's manipulative, he puts himself first. He will convince himself that she's looked after and cared for but he doesn't know that.
