Verwilghen said: "I have never had access to the Madeleine McCann files. "All I can say is as soon as I heard about the case I had deja vu — because it reminded me straight away of Dutroux. "When you look at the case it is of course possible Madeleine was stolen to order. "The alert that was sent looks like it must have come from Belgium police and it should have been taken seriously. "Dutroux investigators uncovered reports of possible pedophile rings operating in Belgium at that time but couldn't finish their enquiry as this was focused on Dutroux, handling him as a lone actor."
