Teams expected to use radar equipment that can scan beneath ground as they look for evidence that could implicate prime suspect Christian Brueckner
A new search for Madeleine McCann is under way in Portugal with police officers gathering a few miles from where the British toddler was last seen in 2007.
Portuguese and German police are carrying out the search 18 years after the three-year-old disappeared from the resort of Praia da Luz while her parents were having dinner out, leaving her sleeping in a nearby room with her toddler twin siblings.
