Detectives investigating the disappearance of Madeleine McCann in 2007 have identified a German prisoner as a suspect.
The Metropolitan Police have not named the man, 43, who is described as white with short blond hair, possibly fair, and about 6ft tall with a slim build.
The German national is known to have been in and around Praia da Luz on the Algarve coast at the time Madeleine vanished on May 3 2007 while on holiday with her parents, Kate and Gerry McCann, and her twin siblings Sean and Amelie.
A half-hour phone call was made to his Portuguese mobile phone around an hour before Madeleine is believed to have gone missing.
The suspect, who is in prison in Germany for an unrelated matter, has been linked to an early 1980s camper van – with a white upper body and yellow skirting, registered in Portugal – which was pictured in the Algarve in 2007.
Scotland Yard said he was driving the vehicle in the Praia da Luz area in the days before Madeleine’s disappearance and is believed to have been living in it for days or weeks before and after May 3.
He has also been linked to a 1993 Jaguar XJR6 with a German number plate seen in Praia da Luz and surrounding areas in 2006 and 2007.
The day after Madeleine went missing, the suspect got the car re-registered in Germany under someone else’s name, although it is believed the vehicle was still in Portugal.
Both vehicles have been seized by German police.
Scotland Yard is launching a joint appeal with the Federal Criminal Police Office of Germany (BKA) and the Portuguese Policia Judiciaria (PJ).
