Madeleine McCann case: Police identify 41 people of interest after combing phone records from Praia da Luz in 2007

Madeleine McCann: The girl was three when she was abducted during a family holiday in 2007

Authorities are trawling through phone records of tourists and residents who were in a Portuguese resort at the time of the disappearance of Madeleine McCann, the Metropolitan Police have announced.

Detective Chief Inspector Andy Redwood told reporters Thursday that police were combing through phone traffic of people in Praia da Luz around 3 May, 2007, when the then three-year-old disappeared.

Scotland Yard says that 41 people of interest have been identified since it began its own inquiry, including 15 UK nationals. Detectives in Britain had issued 31 requests to Portugal and other countries for access to the phone records.

A BBC reconstruction program will be aired this month that authorities say contains fresh and substantive new information.
