A British couple claimed they spotted a bizarre "shrine" to missing Madeleine McCann in the reservoir police searched last week - just seven months after the toddler vanished.
The retired couple, who have asked to be named only as Ralf and Ann, took photographs of the memorial and sent them to Portuguese detectives. The couple felt they were of significance, but never heard back.
The makeshift shrine consisted of boulders in the shape of an arrow pointing towards a picnic site, which was dug over by police last week at the Barragem do Arade in Portugal.
