Police are looking for new clues at a reservoir in Portugal. The area around the Arade dam in Portugal is cordoned off.
TV crews and photographers were only allowed to film or photograph from a distance. According to media reports, even the airspace was closed for safety reasons. The Braunschweig public prosecutor's office is silent about the "clue" that set the large-scale search operation in motion. Investigators suspect that the now 46-year-old Christian B. kidnapped and killed Madeleine.
