It is reported that the information has never been seen by the public before, and could bring some potential new leads surrounding the child's disappearance.
What happened to Madeleine McCann?
Madeleine McCann - at the time three years old - was abducted from her holiday apartment in Praia da Luz, Portugal, on May 3 2007.
At the time, her parents Gerry and Kate were dining with friends nearby and would frequently check on her, and they discovered she was missing during one of the checks at around 10pm.
Her brother and sister, twins Sean and Amelie, were also in the apartment but were not taken.
Ten years later, and the search for the Maddie still continues.
The McCanns were cleared by investigators in Portugal who declared they had exhausted all avenues in the case.
In 2010, Maddie’s distraught parents met with then-home secretary Theresa May to talk about the hunt for their daughter.
The following year, Scotland Yard launched its own review, named Operation Grange, into the case at the behest of the future PM.
Two years later Scotland Yard said it had uncovered new leads while Portuguese police reopened their case.
In October 2015, Operation Grange was scaled down from 29 detectives to just four.
Last December, the Tory government injected extra funding into the operation as cops investigated a new theory that Maddie was snatched by a human trafficking ring.
There have been a string of leads in the case, however nothing has been substantiated.
Has there been any significant leads in the case?
Potential sightings of the British three-year old followed up by British cops total 8,685 across 101 countries and territories, a Freedom of Information request by The Sun showed in October.
However, all have been ruled out.
Over the border in Spain there have been three reported sightings — the latest being in April 2012 — but all have been ruled out.
One of the most serious potential sightings in Amsterdam was revealed when Portuguese police released their case files in August 2008.
It showed a girl of blonde girl of Madeleine’s age and description who told a shopkeeper her name was “Maddie” and she had been “taken from mummy”.
The McCann’s were not made aware of this alleged sighting at the time it was reported to police and it is not clear how - if at all - investigators followed it up.
