Madeleine McCann’s parents are “greatly encouraged” by new information about the disappearance of their daughter, they said in a statement.
A reconstruction of the “latest, most detailed understanding” of the events around the time she went missing will be shown on BBC Crimewatch on Monday October 14.
It comes after the Metropolitan Police revealed a vast log of mobile phone traffic could be the key to finding out what happened to the-then three-year-old.
Scotland Yard detectives, who have interviewed 442 people as part of their review-turned-investigation into Madeleine’s disappearance, hope to track down as many people present in Praia da Luz, Portugal, on or around May 3 2007 as possible.
Madeleine’s parents, Kate and Gerry McCann, said: “We are greatly encouraged by new information coming to light with pieces of the jigsaw now fitting together. We are really hopeful that the forthcoming appeal on Crimewatch will bring further new evidence which will take us a step closer to finding Madeleine and to bringing those responsible for her abduction to justice.”
Earlier this week, Scotland Yard revealed that since launching its own investigation, 41 people of interest have been identified, including 15 UK nationals, up from 38 people of interest including 12 UK nationals established in July.
Detectives have issued 31 international letters of request (ILOR) to mostly European countries in relation to some of the persons of interest as well as accessing phone records.
A large but “manageable” list of phone numbers identified as being present in Praia da Luz – though not necessarily used to make phone calls – has been drawn up by detectives with a “significant” number unattributed to any named person.
And significantly, police officers are now able to create a log showing calls being made at the time of Madeleine’s disappearance.
Madeleine went missing from a holiday apartment as her parents dined at a nearby tapas restaurant with friends.
The Portuguese investigation officially closed but authorities there are backing the Scotland Yard inquiry and officers from both countries will work together in pursuing new leads.
The Metropolitan Police now has a team of six Portuguese detectives based in Faro, who are carrying out inquiries on its behalf.
The McCanns are currently suing former police chief Goncalo Amaral for libel over claims in the book The Truth Of The Lie.
