It's every parent's worst nightmare, to have a child abducted with little hope of ever seeing them again. That's what happened to Madeleine (Maddie) McCann who was taken from her room while her parents dined at a restaurant at a resort in Portugal seven years ago. It was a story that gripped the world, and brought a lot of negative attention directed towards the parents. But now investigators say they have a new lead.

During the period since Madeleine McCann's disappearance, other UK parents have come forward and stated how their children had been sexually assaulted while on vacation in Portugal, five total. One man's description was similar in all the cases, but Maddie was the only one to be taken.
