Woman 'kept as a sex slave' by 'Poland's Josef Fritzl' had all her teeth and both of her LIPS removed, leaving her with 'just a hole for a mouth', as part of captor's 'cruel experiments'

The woman said to have been kept as a sex slave locked in a barn by 'Poland's Josef Fritzl' was horrifically mutilated with injuries including the loss of both her lips and teeth.

The disturbing new details about the suffering of the woman alleged to have been held captive for four years by a rapist monster emerged from the medical reports of the doctors who raised the alarm.

Her alleged captor, Mateusz Jach, 35, was charged last week with mental, physical and sexual abuse, after the woman arrived at hospital to be treated for a dislocated shoulder.

And her account of what happened during her years of captivity suggests Jach was carrying out 'experiments' on her.

The woman also in her thirties - identified only by her first name, Malgorzata - told a fellow patients how she had been repeatedly raped and tortured while locked in the outbuilding in the village of Glogow, west Poland.

And when examined by doctors they found her brutal treatment had left her with such extensive facial damage that she had lost all her teeth and had no lips - while the rest of her body was covered in a variety of abrasions and scars.

The woman had previously been admitted to hospital on several occasions during the years she was held captive - even giving birth to a baby - but she was understood to be too afraid of her captor to tell anyone about her horrifying plight.

And it was only after she arrived last week with her face so badly disfigured - and began to confide in other patients - that doctors treating her finally alerted the authorities and a full investigation was launched.

The baby she had was immediately given up for adoption, apparently against her wishes.

After Margorzata finally revealed her horrific situation, Jach was arrested and is now being held in Glogow prison while investigations take place.

Sources close to the investigation MailOnline: 'While the woman was in hospital, she began talking to another patient about what had happened to her.

'They were speaking in confidence but the patient alerted the doctors about what had happened to her. She is in a really serious condition, both physically and psychologically.

'From what we heard, the girl does not have lips now because of everything he had done to her. Her face is covered in bruises and she just has an open hole [where her mouth is] without the lips.

'The woman said he [Jach] was doing some kind of trial on her. He was experimenting on her. He was trying out different things on her.

'On Monday, she was transferred from a hospital in Glogow to a specialist hospital. We have no idea where but believe it's a psychiatric hospital.'

One of those who saw her last week said that although only in her thirties she looked 'well over 50' due to her physical condition.

As well as the shoulder and the pregnancy - resulting in a baby in 2021 - she had also been taken to hospital on other occasions with both a broken arm and a broken leg.

When asked why hospital officials did not raise the alarm sooner - or question why she was being admitted with so many injuries - they said Malgorzota had 'refused' to contact social services.

Ewa Todrov, spokesperson for the Glogow District Hospital told local magazine Onet they had reviewed her case history in recent days.

She said: 'The woman came to us with injuries indicating that violence could have been used against her.

'Each time we had a conversation with her about it. And each time she swore no one was using violence against her.'

'She categorically refused to notify the services,' the spokeswoman added, claiming the hospital's hands were tied.

Yesterday MailOnline visited the village where the victim was allegedly held for four years.

The barn was divided into two, with a small fake window with lace curtains on one side. Through the window all that can be seen is another wall, which is said to have been filled with insulation and soundproofing.

Tall conifer trees are planted so the barn cannot be easily seen from cars passing on the road, while a sheep's skull lies on a ledge of the building.

At the back of the barn, a dirt track leads out to a forest where neighbours said Jach would be seen at night, sometimes walking through the woods with a flashlight.

Another barn, falling apart,a few metres from the other, would sometimes be covered in curtains at nighttime, with neighbours speculating that is where the victim was washed with a hose.

The pair reportedly met on a dating app in 2019 starting a relationship together, with Malgorzata Jach took her to a disused animal barn on a farm where he lived with his parents.

The victim was subjected to rape, beatings and would be hosed down with water whenever she failed to meet her alleged abuser's demands, it has been claimed.

Despite the barn being located on a quiet residential street in Gaiki, with Jach's parent's house and a neighbours home just a few steps away, his father and mother claimed they never heard any screams.

His father Josef burst into tears as he told Polish media outlet Onet: 'My wife and I really didn't see any girl here. It's a shock for us. It's impossible. It couldn't have lasted years, maybe a few months, but not that long, because it would have been revealed sooner.'

His mother Zofia, who claims she did not know anything, told CrowdMedia: 'There was never a situation when I even thought that someone might be there.

'My husband was in the hospital in Zielona Góra for two and a half months and our son went to see him. If she was there and knew that he was leaving by himself in the car, why didn't she shout? Why didn't she knock?'

Mrs Jach later told Gazeta Wyborcza: 'We didn't go in there at all. There was nothing there at all, so why bother?'

Next-door neighbour Jaigetto Zdzistawa, whose garden runs adjacent to the barn, told MailOnline she also heard no noise but thought Jach was a 'weirdo'.

'My husband works out here in the garden all the time and he never heard anything,' she said. ' If you look through the small window at the end, there are really thick walls and then inside there is another wall.

'Because of the trees surrounding the barn at the front I couldn't see anything and had no suspicions. I couldn't see anything and I couldn't hear anything. The police probably know there is some sort of soundproofing in there.'

Jach now faces up to 25 years in jail in a case that has been compared with one of Austria's most notorious criminals, Josef Fritzl, who kept his daughter captive for 24 years, fathering seven children with her.
