I notice that Correio da Manhā is reporting the telephone links by these drug dealers as significant yet Amaral reported that the only significant calls made the evening Madeleine disappeared were made by Murat. Could this be a case of the PJ protecting informers... and along comes Redwood and spoils it all.
It could simply be that SY had more data to work with than the PJ, or just decided to broaden their search when it came to the cellphone activity in the area.
I'm surprised nobody noticed this little tidbit at the end of the article translated by Joana Morais:

The PJ, meanwhile, has discarded Euclides Monteiro as primary suspect, and believes now, that the man who may have taken Madeleine, was a foreigner that has committed an isolated crime, at a time when he was spending his holidays in Portugal.
So either the PJ believes that Maddie was simultaneously abducted by the eight local lowlives and by the foreign holidaymaker or...
Or their real suspect is said holidaymaker and the eight locals are just the persons of interest with potentially important knowledge.
The interpretation that I made of that information is that the PJ is only interviewing/questioning those eight local "lowlifes" because of the SY investigation and their request. The fact that it came out that the PJ "believes now, that the man who may have taken Madeleine, was a foreigner that has committed an isolated crime, at a time when he was spending his holidays in Portugal," shows how the investigations of the two police forces are heading in different directions.
Also, we can't be sure that SY believes completely that those three/eight people are responsible for Madeline McCain's disappearance or if they are just questioning them as possible witnesses.
Cheers,
