The suspect in the Madeleine McCann case has been moved to solitary confinement to protect him from fellow prisoners.
Christian Brueckner, 43, is also receiving counselling on how to deal with intense media scrutiny.
The former car mechanic and convicted paedophile is in a high security prison in the northern German city of Kiel on drugs charges. He was identified as a suspect in the Madeleine case last week, more than 13 years after the little girl went missing on holiday in the Algarve.
And yesterday the German prosecutor running the investigation revealed his team has not shared all their evidence with their Portuguese counterparts.
Hans Christian Wolters said he believed the Portuguese still harbour suspicions about Madeleine's parents, Kate and Gerry. The couple, from Rothley in Leicestershire, were infamously named as "arguidos", or suspects, after their 3-year-old daughter's disappearance.
