Woman woke up in bunker after date knocked her out with drugged strawberries

A woman thought she would never escape after a doctor drugged and kidnapped her to keep her as a sex slave in a basement on his farm.

Isabel Eriksson didn’t even know if she was above or below ground when she woke up in a soundproofed cell with a cannula in her arm.

All she could see was a ‘tin roof and a man sitting on a chair next to me, just looking at me’, she said in a 2017 interview.

‘I tried to attack him to escape. I attacked him with two spikes but I was still sedated, so it was not a good attempt.

‘He said that if I try again he would fix me up in chains in bed and feed me only with crispbread.’

Posing as an American stock trader, Dr Martin Trenneborg had drugged the £2,000-a-night escort with Rohypnol-laced strawberries dipped in chocolate while on a date, before driving 350 miles from her Stockholm flat to a remote farm in southern Sweden.

There he intended to keep her for a decade in a self-built 60sqm bunker with walls 30cm thick and a door he described as like a ‘bank vault’ which she would ‘never be able to open’.

During his trial in 2016, Isabel said: ‘He asked me if I had any wishes, whether he should expand the bunker… because I will be living here for many years.’

He made clear his intention to use her as ‘a girlfriend’ who would ‘have sex two or three times a day, clean and cook’, she told the court.

In a new Swedish miniseries – ‘The Bunker’, on streaming platform ‘Viaplay’ – she said: ‘I was completely panicked. I felt powerless.’

While the doctor worked as a freelance physician, he would leave Isabel in the bunker, kitted out with a bedroom, toilet, kitchen, and a courtyard covered so the neighbours couldn’t see when he took her there each morning.

He would return in evening, often disguised in masks and theatening to kidnap Isabel’s mother if she refused his commands.

Trenneborg would also withdraw blood from Isabel, and take vaginal samples to test at his workplace.

He did this to see if she had STDs. Isabel said: ‘He said that he wanted to have unprotected sex with me.

‘I got some pills from him, it was birth control pills and he told me that he did not want me to get pregnant.’

Isabel’s ordeal came to an end after six days when Trenneborg, now 47, panicked at the sight of news reports about her disappearance and his face reported with them.

Driving her to a police station in Stockholm, he told Isabel to stick to a cover story.

But in the interview room, away from her captor, she revealed what he had done.

Trenneborg was sentenced to 10 years in prison after he admitted kidnapping her.

Despite also being charged with rape, which he denied, a trial found insufficient evidence to convict him of this.

Isabel told her story in a 2017 book titled You Are Mine, and she has gone on to launch a £12-a-month OnlyFans page where she posts ‘artful’ photos of herself posing semi-naked.

She told MailOnline: ‘My OnlyFans site is my way of dealing with the trauma that I am still facing even after all these years.

‘I have always been very creative and posing for these pictures which are artful and tasteful, is my way of dealing with the stress that I went through.

‘I’m not totally naked in any of the photographs, I have my underwear on, and they are no way pornographic.

‘They are beautiful, sensual photographs, which reflect my creative artistic passion, and which have helped me cope with the severe PTSD I was left with.

‘We should be proud of our bodies, and we are all a piece of art, and we are all beautiful and if you want to manifest that for yourself and others than that’s great.’
