A Polish man has been sentenced to 25 years in prison after he was found guilty of locking up his wife and allowing his siblings to repeatedly rape her.

Investigators found Mariusz Sz, from the small village of Parszczyce in northern Poland, sexually assaulted his wife between 2006 and 2010. He even locked the victim up in a dark cellar for over two years and charged 20 PLN ($5) from his brothers Andrzej and Marian Sz, and their friend Tadeusz B, every time they allegedly wanted to rape her.

During the time when she was forcefully restraint by Mariusz Sz, the victim was brutally beaten, starved and not allowed to wash herself. The accused put a bag over his wife’s head so she was unaware of who was raping her when she was “rented” out by her husband. It is not yet clear as to how many people raped the victim.

The victim had two daughters and was in constant fear about their safety. Eventually, she managed to escape from the cellar and call her mother. However, when she approached the police to file a complaint against her husband, she was turned away three times before the authorities finally launched an investigation into her claims.

Before announcing the verdict, presiding Judge Marta Urbanska read out some of the details of the horrific conditions the victim was subjected to, including enduring "physiological needs under undignified conditions" while being “imprisoned in a cold, dark cellar." The judge added that the woman was fed bread mixed with her husband’s semen.

"She was starved, forced to eat meals with her bound hands in a kneeling position,” Urbanska said. "Meals were prepared in a manner that denied her dignity."

Mariusz Sz has been dubbed as the Polish Fritzl, alluding to Austria's Josef Fritzl who was imprisoned for life for holding his daughter, Elisabeth, captive for 24 years and repeatedly raping her. 

Andrzej, Marian Sz and Tadeusz B were charged with rape and will face a minimum of three years and maximum of 15 years in prison if found guilty. All of them pleaded not guilty to the charges. Their trials are ongoing.
