Tuesday's search appears to have focused on an abandoned building, where officers were seen digging and clearing rocks. Timeline: Madeleine McCann disappearance The search - which covers the municipality of Lagos, near Praia da Luz - is due to continue until Friday. German authorities fear that if Brückner is not charged with anything, he will disappear following his release. They said they will hand over any evidence seized in the latest search to German authorities. The last search took place two years ago and was focused around a reservoir to the north-east of where Madeleine was staying.
