The main suspect in the loss of Madeleine McCann faces new unrelated accusations, the BBC reportedly.
Christian Bruckner is scheduled for next week in a court accused of shaming members of prison staff.
The exact details of the claim have not been made public.
If convicted, court officials say the current sentence could be extended, which is expected to end in September.
Bruckner, 48, is behind a German bar after raping a 72-year-old American tourist in Portugal in 2005. He has never been charged in McCann’s case and has denied any involvement.
Three-year-old Madeleine McCann disappeared from Praiadals’ holiday apartment in Portugal’s Algarve region in 2007.
It has become one of the most famous and unresolved shortages in the world.
Bruckner was not identified as a suspect in her loss until 2020.
German investigators classified the incident as a murder investigation.
However, in the McCann case, no charges have been filed against Bruckner, and no details of the suspicious evidence have been released.
A convicted child sex offender, Bruckner is a German citizen with a history of gender, counterfeiting, drugs and theft.
A castaway man, he lived in the Algarve region of Portugal for years.
Currently, Bruckner is set to walk freely in September 2025, so prosecutors are hostile to the clock.
Investigators fear that Bruckner, as a free man, will skip Germany and disappear.
Last year’s ruling paved the way for his release when he was acquitted from five other sexual offence allegations.
In October 2024, the judge cleared Bruckner out of three counts of rape and two counts of child sexual abuse.
Prosecutors have launched an appeal, but decisions on a potential retrial could still take months.
Bruckner is expected to face accusations of contemptting prison officials in court in Lethe, Lower Saxony on Thursday morning, court officials told the BBC.
If convicted, Bruckner could face a fine or even a year in prison.
Bruckner’s interest in legal battle continues to rise as his name is tied to the loss of Madeleine McCann.
Prosecutor Hans Christian Walters told the BBC he was aware of future unrelated trials in the Lethe District Court, but was being handled by another office.
He also reiterated that there are no plans yet to claim Bruckner for the McCann case.
In 2020, Wolters told the BBC that if he “knowed the evidence we had,” he would reach the same conclusion as his team about Brückner’s alleged involvement.
The BBC requested comment from Christian Brückner’s legal team.
