Four suspects have been arrested in connection with the disappearance of Maddie McCann.
The suspects arrived at Faro Police station on the Algarve for questioning over the disappearance of the little girl who has strong Donegal connections.
The suspects will be quizzed by local police in the presence of Scotland Yard officers who claim they are getting closer to the truth of how little Maddie disappeared.
Those arrested are said to be three Portuguese nationals and a Russian computer expert, whose Praia da Luz home was searched by police shortly after Madeleine went missing in May 2007.
Detective Chief Inspector Andy Redwood arrived just before 9am today to lead a team of around half a dozen Scotland Yard officers.
It is understood that eight other people, thought to be mainly former workers at the Ocean Club holiday resort where Madeleine vanished during a family holiday, are also due to be questioned as witnesses.
The police questioning is expected to last until Friday.
It comes less than three weeks after police dug up waste land near the Ocean Club and inspected sewers using a hi-tech camera over nearly a fortnight in a grim search for Madeleine’s body.
The search and this week’s police quizzes have happened at the request by Operation Grange detectives leading the British hunt for Madeleine.
Scotland Yard are working on the theory burglars killed Madeleine during a bungled break-in while her parents ate dinner with friends 100 metres away – and then buried her body on waste ground in the resort.
