German prosecutors have said items seized as part of fresh searches for evidence in the Madeleine McCann case cannot yet be linked with the investigation into her disappearance.
A large section of the Barragem do Arade reservoir in Portugal was cordoned off last week, about 30 miles from where three-year-old Madeleine went missing in 2007.
Police flattened a specific area of woodland and dug a number of holes near the remote reservoir as part of the three-day hunt for evidence.
