The prime suspect in the disappearance of Madeleine McCann has complained about "awful conditions" in prison while on trial for a series of sex offences.
Christian Brueckner - who is charged with offences unrelated to McCann - has reportedly "moaned" about the impact of his trial.
He is on trial for the suspected rape of three women and twice sexually molesting children in Portugal.
The convicted rapist believes a "police game" has been designed to "make him crack", a source has said.

"Brueckner has been moaning a lot about the impact this trial has had on him," the source told The Sun.
"He thinks he is paraded as part of a game police are playing and that the whole thing is just designed to try and make him crack up.
"He knows the police want him to confess to things he’s not responsible for."
It comes after his trial was suspended last week after his lawyer claimed a judge had called for the assassination of a president.
LATEST DEVELOPMENTS:
During a rant his lawyer, Dr Friedrich Fülscher alleged that one of the lay-judges was biased and claimed she had called for the assassination of a president on social media.
He said the woman had written “kill the b*****d now” and "kill the devil", in reference to former Brazilian leader Jair Bolsonaro.
The source added: "No-one has any sympathy for him, apart from his legal team. They have raised concerns on his behalf about the awful conditions he says that he’s being kept in while behind bars.
"He’s forever moaning about his cell and the risk he is at from other inmates."

PABrueckner has been charged with the rape of a woman in her 70s in her home in the Algarve and the rape and sexual assault of a teenage girl.
He also faces allegations that he raped a young woman, at knifepoint in her home, in 2004 - an act he is accused of recording on video.
The court also heard that he masturbated in front of a girl at a playground in Messines in June 2017 and faces claims he did the same in front of another girl, on Salema beach, Portugal, in April 2007.
Brueckner is already in German prison for raping a woman in the part of Portugal's Algarve region where three-year-old Madeleine went missing.
