MADELEINE McCann, suspected by Christian B., stated that the prisoners were threatening to kill him in a moaning letter published by the German press.
A suspect is in jail in Germany in connection with the rape of a 72-year-old American tourist.
Christian B. also complained about having to buy his own pens and the lack of coffee creamer.
The 44-year-old man, who has not been charged with Madeleine’s disappearance in 2007 but has been identified as a suspect, filed a complaint in a 14-page letter.
Post posted Builddetails how Christian B.’s cellmates now know who he is thanks to a documentary linking him to Madeleine’s disappearance.
He claims he is being bullied and threatened with death.
In one case, according to the letter, a man approached Christian B. in the yard and threatened to kill him.
“I force myself to self-isolate because there is a high possibility of physical attack from inmates,” he said.
“This is torture.”
Christian B. claims to only leave his cell for one hour a day for fear of being killed and avoids certain areas of the prison.
He also complained that the prison guards had confiscated his pens and complained about the lack of coffee creamer.
This is because the 11-year investigation into the disappearance of Madeleine by Scotland Yard came to an end at the end of this year.

A source told The Sun that there are “no plans at this time” to continue Operation Grange.
This decision means it is unlikely that prime suspect Christian B. will be charged with her disappearance.
This highlights that high-ranking police officers believe that there is not enough evidence to initiate a case against a convicted pedophile and rapist, who, according to the German police, is not involved.
The source added: “The end of the path of Operation Grange is already in sight.
“The work of the group is expected to be completed by autumn.”
The source said the case files could be reopened if any important new information comes to light.
The Grange investigation was launched in May 2011 – four years after Madeleine’s disappearance – after her mother Kate wrote an open letter to then-Prime Minister David Cameron in The Sun asking British police to launch an investigation.
Current funding for the investigation ends March 31st. The Met’s latest request for another grant, running through the end of September, was recently submitted to the Home Office.
The total cost of the investigation is around £13 million.
