'Eight leads' in Madeleine search
Spanish private detectives claim they have handed Scotland Yard up to eight "very important leads" in the search for Madeleine McCann.
Four Metropolitan Police officers held talks with Barcelona firm Metodo 3, which investigated her disappearance on behalf of the family, sources said.
Officers travelled to Spain to pick up around 30 boxes of documents, investigator Francisco Marco Fernandez told Spanish TV.
Mr Fernandez, who was hired by parents Kate and Gerry for six months, told the Ana Rosa Programme he provided police "with all the documents and information we have collated worldwide about Madeleine's disappearance".
"I think there are six, seven or eight very important leads in there," he added.
A Scotland Yard spokesman refused to confirm the meeting took place.
"We will not be providing a running commentary," he added.
Family spokesman Clarence Mitchell added: "Kate and Gerry will simply not be commenting whilst the Metropolitan Police review of Madeleine's case is under way.
"They remain pleased that the Met team is continuing its work and that progress is being made."
It is the second time officers are understood to have visited the Spanish city.
