The main suspect of the disappearance of Madeleine McCann faces a new unrelated position, has been told to the BBC.
Christian Brückner is due in the Court next week accused or insulting a member of the prison staff.
The precise details of the accusation have not been made public.
If you declare guilty, you could extend your current prison term that you must end in September, according to a court official.
Brückner, 48, is behind bars in Germany for violating an 72 -year -old American tourist in Portugal in 2005. He has never accused in the case of McCann and denies participation.
Madleine McCann, three years old, disappeared from a holiday apartment in Praia da Luz, in the Algarve region of Portugal, in 2007.
It has become one of the cases of missing people with the highest profile and unsolved in the world.
Brückner was not identified as a suspect in his disappearance until 2020.
German researchers classified the case as a murder investigation.
However, no positions has brought Brückner, in the case of McCann, and all the details of the alleged evidence have never released.
A convict child sexual offender, Brückner is a German citizen who has a history of sex, falsification, drugs and robbery crimes.
Drifter, lived in the Algarve region of Portugal, inside and out, for years.
Now prosecutors are working against the clock, since Brückner plans to walk for free in September 2025.
Researchers fear Brückner, as a free man, jump to Germany and disappear.
A ruling, last year, raided the way to release when it was acquired by five other accusations of sexual crimes.
In October 2024, the judges clear Brückner of three rape positions and two positions of child sexual abuse: charges that date between 2000 and 2017 in Portugal.
Prosecutors have launched an appeal, but a decision on any possible new trial can take months.
Brückner must deliver in the court on morning in Lehrte, Lower Saxony, to face the position of insulting a member of the prison staff, a court official told the BBC.
If you are guilty, Brückner could face a fine or up to an additional year in jail.
The interest in Brückner’s legal battles remains high because the authorities link their name, to the disappearance of Madeleine McCann.
Prosecutor Hans Christian Wolters told the BBC that he was aware of the next unrelated trial in the Lehrte district court, but is handled by a different office.
He also reiterated that there are still no plans to charge Brückner for the McCann case.
In 2020, Wolters told the BBC that the public would reach the same conclusion as his team, about Brückner’s alleged participation, if “they knew the evidence we had.”
The BBC has approached Christian Brückner’s legal team to comment.
