Portuguese police have started investigating an area just nine miles from where Madeleine McCann was abducted after a tip off from a Dutch source.
An anonymous note, seemingly from the same person who sent a letter leading police to the bodies of two murdered Belgian girls last year, was received by a newspaper and passed to the Policia Judiciaria.
It claimed the four-year-old lies buried under rocks and branches in deserted scrubland.
A map marking the location of Madeleine with a cross was sent along with the letter.
It was thought to pinpoint an area north of Odiaxere, north east of Praia da Luz from where the girl was snatched 41 days ago.
Around eight plain clothed police officers later visited Arao, a small village 15 kilometres away from Praia da Luz.
They spent an hour and 20 minutes looking at fields and the surrounding area ahead of possible searches starting in the morning.
Local Translator Gaynor Jesus told Sky News: "Apparently the letter came from a medium who pinpointed the location of two murdered Belgian girls - I think this is the reason for such credibility.
"But in Portugal mediums' reports are filed away unless they have something specific police can go on - they have received hundreds reports.
"They are treating this report with extreme caution."
Chief Inspector Olegario Sousaadded: "We are checking the information like we check everything in this case for importance."
Meanwhile, Madeleine's family announced that hundreds of yellow ribbons, cuddly toys and messages of support left at a memorial for Madeleine McCann are to be cleared away.
The colourful tributes have been placed around a monument in the centre of the four-year-old's home town of Rothley, Leicester, ever since she went missing 41 days ago.
The memorial has been a focal point for those praying for the little girl's safe return.
Madeleine's great uncle, Brian Kennedy, said: "We are aware that the huge response to the loss of our great-niece Madeleine has changed the appearance of Cross Green in the centre of Rothley for several weeks now.
"We would like to restore the Green to something approaching normality, whilst acknowledging the kindness shown by so many people."
Mr Kennedy said the family hoped to initially clear seats around the green and to move as many of the donated toys as possible to a good home for other children.
"All the cards and messages will be stored carefully to await the family's return and some have been sent to them already."
Pub landlady Valerie Armstrong, who arranged for well-wishers to tie yellow ribbons to railings around Cross Green monument, said the process would begin at the weekend.
She said: "It's definitely not a sign of us giving up hope. It's just the practical side of it. We need to free up some of the benches. The yellow ribbons are staying."
