At least four suspects were to be questioned in Portugal on Tuesday by police investigating the disappearance of Madeleine McCann, sources close to the case said. British detectives arrived at a police station in Faro where they are expected to sit in on interviews conducted by Portuguese offices, ITV News reported. Detectives from London’s Metropolitan Police will be allowed to intervene during questioning if they wish.
The suspects are all Portuguese nationals but some are Russian-born, the source told NBC News. All will appear voluntarily and the questioning could last for days. Key witnesses will also be questioned. The three-year-old British girl vanished while holidaying with her parents in Praia da Luz in 2007. In early June, police searched three sites in the resort but found no evidence relating to the case. The developments come after a new investigation into the case was launched last year.
