Man who exposed Jimmy Savile believes Madeleine McCann left apartment on her own on night she disappeared

For years, people have been trying to work out what happened to Madeleine McCann.

"And my conclusion is that on that night of Madeleine's disappearance, she woke up, looking for mum and dad, and she'd been told the following morning that if she were to wake up, the parents were only in the tapas bar, which was just across the courtyard.

"What we do know is that her brother and sister had woken up on the previous nights a number of times, and I suspect as a result of that, Madeleine thought, well, where is mum and dad, as they'd been out on those previous nights as well."

Williams-Thomas went on: "So I believe she woke up, she left the apartment, we know the apartment was insecure, the back patio door was open to allow some flow of air, it was very hot.

"And so I believe she got up and went wandering looking for her parents."

Williams-Thomas explained that Maddie would have had to have gone out onto a main road in order to get around to the courtyard, where her parents were.

And citing two infamous cases in the UK - Genette Tate, who vanished in 1978, and Sarah Payne, who was murdered in 2000 - Williams-Thomas explained that it was most likely an unplanned abduction.

He said: "What we know about abductions is when they are stranger abductions, they are opportunistic.

"If you abduct a child and you know who that child is, which is the majority of child abductions, then, of course, that's planned and you know who the child is.

"But when it's opportunistic, when it's not somebody known to the child, that is not planned, in terms of who the victim is."

Adding: "So I believe she walked out on the road, and in a matter of seconds, was abducted by a predator outside."
