I think we should be informed of the sources your "information" emanates from since it is obvious you think it is superior to that which is available to the rest of us.
Just common sense, Brietta. The story was given to the UK press on 1st October and Amaral was asked about it on 2nd. He denied the PJ were investigating it, despite what David Brown claimed;
A maid who is alleged to have abducted Madeleine McCann in revenge for being sacked from the holiday resort where the missing girl was staying is being investigated by Portuguese police.

A police source told London newspaper The News of the World: "There have been hundreds of Madeleine theories, sightings and tips sent into UK cops from members of the public. But this one is different.
"It's incredibly detailed and so far, from the inquiries being made in Portugal, it appears to be based on factual events."
https://themaddiecasefiles.com/royal-tip-in-search-for-maddie-courier-mail-aus-01-t18500.htmlThe answer has got to be no-one, because the UK police weren't allowed and there's nothing to suggest the PJ were either informed or interested.
Amaral shouldn't have made the remarks he made, but I can understand why he did.
