BRITISH detectives investigating the disappearance of Madeleine McCann have flown to Portugal to discuss potential leads with local officers, it is reported.
The team from Scotland Yard officers travelled to the Algarve after a letter was sent to police in the country asking for help to trace three burglars spotted in the area where Madeleine vanished almost seven years ago, Sky News said.
The team, headed by Detective Chief Inspector Andy Redwood, who is leading the Met's investigation, reportedly met members of Portugal's Policia Judiciaria and prosecutors to request help and discuss leads identified by teams in the UK.
It is reported that they are seeking assistance to interview the three potential suspects, though Scotland Yard refused to confirm whether a team was in the country or the purpose behind the travel.
It is reported elsewhere that three men are set to be arrested, while the McCanns are on 'tenterhooks'
Mobile phone records reportedly revealed that the suspects repeatedly called each other in the hours after three-year-old Madeleine disappeared from a holiday apartment in Praia da Luz in May 2007.
British officers have travelled to the Algarve numerous times since then in the search of the missing girl.
The Portuguese shelved the inquiry into her disappearance in 2008, but in October said that a review had uncovered enough new information to justify reopening the case.
Television appeals in the UK, Germany and Holland last year triggered thousands of calls from the public.
Metropolitan Police Commissioner Sir Bernard Hogan-Howe called for a joint investigation between British and Portuguese police to find out what happened to Madeleine.
