British detectives investigating the disappearance of Madeleine McCann have been given permission to question eight suspects.
They include three burglars – who are also convicted drug dealers – The Sun reports.
The trio were found to have been in Praia da Luz at the time of her disappearance.

Mobile phone records revealed they had made an unusually high number of phone calls to each other shortly after she vanished.
In the days before Madeleine’s disappearance, the trio in question are reported to have raided another holiday flat in the same resort, awakening a child, but fled after the parents returned.
The Portuguese police attached no significance to the earlier incident, but one theory is that the burglars may have panicked after waking Madeleine by mistake and decided to take her with them.
The remaining five suspects are understood to include staff who worked at the Ocean Club resort where the family was staying in 2007, the newspaper adds.
The search entered its fifth day on Friday
It is understood the questioning will take place after the current searches have concluded.
Friday marked the fifth day of investigations on a patch of scrubland close to where the little girl was last seen.
Items of clothing are believed to have been retrieved from a hole in the ground, though they are thought to have been ruled out of the investigation.
Sniffer dogs used in the hunt for murdered schoolgirl April Jones have also been brought in, as has ground penetrating radar equipment.
Madeleine, who was then nearly four, disappeared from her family's holiday apartment in Praia da Luz in Portugal's Algarve on May 3 2007, as her parents dined at a nearby tapas restaurant with friends.
