Police have said materials unearthed during a three-day hunt for evidence over the disappearance of Madeleine McCann at a remote reservoir in Portugal are being sent off for analysis.
Authorities have been scouring Barragem do Arade reservoir in the Algarve this week, using sniffer dogs and cutting down trees as part of the search inland from the coastal resort where the then-three-year-old went missing in 2007.
