«Detective Chief Inspector Andy Redwood, who is leading the investigation, said the analysis of mobile phone data originally collected by the Portuguese had gone beyond the stage of a general trawl, and was now being cross-referenced with other information.
His team have been cross-referencing tens of thousands of documents, communications data and witness statements from the Portuguese investigation, from eight private detectives and from the Leicestershire force.
The mobile phone data is a substantial amount of data and a significant amount of it is unattributed. Putting this with layers and layers of other information, we are carrying out a targeted attack on the information. We are doing this in a focused way, working back from the moment that Madeleine was found to have gone. It is like pulling back the layers of an onion. Every hour my officers work on this case is designed to get to that very moment and find out what happened.»
