Detectives from London's Metropolitan Police are in Portugal to meet with their counterparts there, the Daily Telegraph reported Wednesday. Investigators have suggested arrests in the case of the missing British girl are possible.
Madeleine, then 4, was sleeping with her siblings in the family's holiday apartment when she vanished. Her parents were eating with friends at a restaurant in the resort where they could see the windows of the apartment.
The Daily Mirror reported three men have been identified as potential suspects. All were in the area when Madeleine disappeared and made numerous calls to each other immediately afterward.
