Police have launched multiple searches for Madeleine McCann since her disappearance in Portugal in 2007.

Early efforts focused on the Praia da Luz resort, where she was last seen in her family’s holiday apartment.

In 2013, British police began Operation Grange, a formal investigation into the case. Searches have included digging in scrubland, draining reservoirs, and using sniffer dogs and ground-penetrating radar.

German authorities have also led inquiries in recent years, targeting prime suspect Christian Brückner.
