Four suspects in the case of missing British girl Madeleine McCann have arrived at a Portuguese police station to face questioning.
The four men, said to be three Portuguese nationals and Russian computer expert Sergey Malinka - will be questioned by police about Madeleine's disappearance in 2007.
Scotland Yard officers will sit in on the questioning at Faro police station, but will not be able to ask questions, BBC reported yesterday.
Malinka had previously been involved in the case when his Portuguese home was searched shortly after Madeleine went missing. He was not listed as a suspect at the time and denied any involvement, the Daily Mail reported.
Eight other people, most of them workers at the resort where Madeleine disappeared while on holiday with her family, would also be questioned as witnesses.
The latest round of investigations is being handled by a team of London-based Scotland Yard officers who spent two weeks digging up wasteland in a search for clues about Madeleine's disappearance.
The British investigators have been exploring the possibility Madeleine was killed during a bungled break-in, and her body then disposed of. Both the search and the latest round of questioning has come at the request of Operation Grange detectives leading the British hunt for Madeleine, the Mail reported.
It is not clear if new searches will be undertaken, though a Portuguese newspaper said sniffer dogs used in the wasteground search have been brought back into the country.
Portuguese newspapers also say local police are not investigating any of the four new suspects, and are working on the theory Madeleine was kidnapped by a foreigner and taken out of the country.
The police questioning is expected to last until Saturday.
