I found the following snippet from Reuters of interest given recent discussion of knowledge and awareness of CB in the investigation.
The judicial police claim to have passed the name to the Brits in 2012. One wonders was that it? Or did they add context?
Taken from Reuter's article
For the first time since 2007 Portuguese prosecutors in Faro identified an official suspect in the MM investigation. The prosecutors did not clarify their reasons but said that the investigation has been carried out with cooperation from British and German authorities.
CB lived in the Algarve between 1995 and 2007 and burgled hotels and holiday flats etc, information verified by Reuters who had sight of court documents in 2020.
They also reported that “Portugal's Judiciary Police handed over documents with hundreds of names related to Madeleine's case,
including CB to British authorities in 2012, according to the force.”
Portuguese prosecutors said on Thursday a man had been formally identified as a suspect in the disappearance of British toddler Madeleine McCann 15 years ago.
