A former Yazidi sex slave came face-to-face with her ISIS captor after escaping captivity to flee to Germany but was told that police could do nothing because he was a refugee, it has been claimed.

Ashwaq Ta'lo was kidnapped by ISIS in August 2014, aged 15, and was kept in captivity by the jihadist man for three months but escaped and made her way to Europe.

Speaking in a Facebook video, she said she had seen the man, Abu Humam, in 2016 and then again earlier this year in Schwäbisch Gmünd in south-western Germany.

She told police and asylum officials about the encounter and although they identified the man from CCTV they said there was nothing they could do because the man was also registered as a refugee, The Times reports.

Ashwaq was reportedly taken into Syria with 65 members of her wider family and was sold to Abu Human, a Syrian ISIS member, for $100.

After being abused and forced to convert to Islam she walked 14 hours by herself to flee from captivity before she claimed asylum in Germany.

But she has now fled the country after the terrifying encounter with the man who had enslaved her.

She said in a video she had pretended to be Turkish after he had spoken to her in German and Arabic and told her: 'I know where you live'.

'I was so scared, I could barely talk. I thought that in Germany it doesn't matter what I do. Nobody cares. I thought it's over for me.

'He started speaking in German, asking if I'm Ashwaq or not. I said no, then he started speaking Arabic.

'I continuously replied in German, saying I don't speak Arabic. I pretended to be Turkish, saying I only speak Turkish and German.

'He then said: 'I know that you've lived in Germany since 2015. I know that you live with your mother and your brother.'

'He even told me my own address. In short, he knew about my whole life.'

Ashwaq said many Yazidi girls who had fled to Europe had later encountered the men who had put them in captivity.

She said she had a friend in nearby Stuttgart who had also seen her former captor.

Ashwaq thanked her hosts in Germany, saying: 'Apart from that, I thank all Germans. I've been in school for three years and I've learned so much. I thank you all.'

The Yazidis, a Kurdish ethnic group, have suffered massacres and oppression for generations and the Kurdistan region in northern Iraq has been under siege from ISIS since 2014.

The UN has declared the killing of the Yazidi people by ISIS as genocide with many women raped by jihadi fighters.

Some 7,000 Yazidi women and girls were forced into sexual slavery when the militia took over the community’s heartland in Sinjar, northern Iraq, and slaughtered 5,000 people.

Earlier this year a German intelligence chief warned of the 'massive danger' posed by women and children returning 'brainwashed' from fighting with ISIS.

Hans-Georg Maassen said in February that Germany should consider repealing laws restricting surveillance of minors under the age of 14 to prepare for the increased risk of attacks by children as young as nine.
