Portuguese police are reported to have received a tip off about a Madeleine lookalike in a town in Malaga. Specialist officers are understood to have received the tip-off that a girl ressembling Maddie was spotted in Nerja, 30 miles east of Malaga, 10 days ago.
Scotland Yard detectives reviewing the 2007 disappearance of Madeleine from a holiday flat in Praia da Luz are said to be liaising with their Spanish counterparts about the latest lead.
McCann family spokesman Clarence Mitchell said: "Kate and Gerry are aware of this particular report from Spain. It was absolutely right that the police investigate any potential lead.
"Kate and Gerry remain very grateful for the co-operation of the police in the search for Madeleine."
Malaga-based Sur newspaper reported the possible sighting is being handled by the specialised and violent crime unit of Spain's judicial police
There have been numerous 'sightings' of Madeleine since she disappeared almost five years go. The most recent was in July last year, when DNA tests were taken from a little girl in India.
But the girl was not Madeleine.
