Madeleine McCann disappearance

As detectives conclude a three day search, optimism fades in Praia da Luz.

Authorities carried out a fresh search near where the three-year-old vanished in Praia da Luz in 2007.

Investigators have until Friday to look for evidence relating to her disappearance from Praia da Luz 18 years ago.

The search so far has focused on derelict, abandoned buildings and wells.

Searches have resumed in Portugal nearly two decades after the three-year-old went missing.

Police are searching an area where prime suspect, Christian Brückner, stayed at the time of Madeleine's disappearance.

Authorities say the new search will be across 21 plots and will continue until Friday.
