Files containing reported sightings of missing girl Madeleine McCann - including one in New Zealand - should be handed to investigators still searching for her, a family spokesman says.
Several British newspapers report that thousands of previously unseen pages of information passed to police after the case was closed had been released to them after they applied to a Portuguese court.
"Kate and Gerry [Madeleine's parents] have made it clear that they were shocked to see the lack of follow-up work done by the Portuguese police since the investigation was shelved", said family spokesman Clarence Mitchell.

"All the information in these files must go to the private investigators as they are the only people still looking for Madeleine."
Portuguese police are no longer investigating the case, but private investigators are still looking for the missing girl and appealing to the public for information.
Fresh leads reported by the newspapers, including the Daily Mail and the Daily Express, include security camera footage in New Zealand showing a girl resembling Madeleine being led into a supermarket by a man.
Other reported sightings crop up in Portugal, Spain, France and the United States.
Madeleine went missing from a holiday apartment in the Algarve resort of Praia da Luz on May 3, 2007, a few days before her fourth birthday, as her parents and their friends dined at a nearby restaurant.
The McCanns were named as official suspects in her disappearance in September 2007 although this was lifted in July 2008.
