Potential new clues in the Madeleine McCann case have been passed to British detectives on the fifth anniversary of her disappearance.
Logs of around 100 pieces of information sent to Crimestoppers have emerged that were never sent to investigators in Portugal or the UK.
The logs contain details supplied by psychics and others who claimed to have dreamed what happened to Madeleine.
The information was sent to a special Crimestoppers hotline set up a week after Madeleine vanished in May 2007.
For several months all of it was passed to Leicestershire Police, the McCanns' home force, who were investigating UK angles.
But sources say the force was so inundated with information it asked Crimestoppers to stop sending details supplied by psychics and dreamers.
Now it has been discovered the logs were never sent to any of the investigation teams.
A source said the material may prove of no value at all, but it was important it was at least looked at.
"Psychic stuff is often very precise and is therefore easily eliminated, if nothing else," the source said.
"But sometimes it can corroborate more tangible information already in the system."
Another source said sometimes witnesses claim to have learned details through psychic powers just to distance themselves from what they know.
Scotland Yard said: "We are in close dialogue with Crimestoppers to ensure that all material in their possession - from any source - is shared with us."
Madeleine went missing exactly five years ago from an apartment in the Algarve region of Portugal.
On Wednesday, Madeleine's parents told Sky News they were more hopeful than they had ever been that their daughter will be found alive.
Kate and Gerry McCann also said they were confident the abandoned police investigation would be reopened by the Portuguese authorities soon.
Police have released an age-progressed image of how Madeleine could look today, aged nine.
A statement issued with the photo said: "As a result of evidence uncovered during the review they now believe there is a possibility Madeleine is still alive and are appealing for anyone who is able to provide direct information as to her whereabouts to contact the team."
The three-year-old disappeared just days before her birthday from the family's holiday apartment in Praia da Luz. She has never been found.
Anyone with information is urged to call their local police, Scotland Yard on 0207 321 9251 or Crimestoppers in confidence on 0800 555 111 . They can also email
