German police had previously said Christian Brueckner, 44, was probably responsible for toddler’s disappearance in 2007

A German man has been formally identified as a suspect in the disappearance of British toddler Madeleine McCann 15 years ago, Portuguese prosecutors have said.

Christian Brueckner, a convicted rapist, has been made an “arguido”, translated as “named suspect” or “formal suspect” who is treated by Portuguese police as more than a witness but has not been arrested or charged.

The German’s lawyer said that his client has not been charged over the case.

Prosecutors in Faro did not publicly name the man but said in a statement he was identified as a suspect by German authorities at their request.

The timing of the move could be related to Portugal’s 15-year statute of limitations for crimes with a maximum prison sentence of 10 years or more. Madeleine disappeared on 3 May 2007, while on holiday with her parents in Praia da Luz in Portugal.

It is the first time that Portuguese prosecutors have identified an official suspect in the case since Kate and Gerry McCann, Madeleine’s parents, were named suspects in 2007. They were later cleared.

Prosecutors said the investigation has been carried out with cooperation from British and German authorities.
