A woman who was kidnapped by ISIS as a teenager in her native Iraq in 2014 and held for three months as a sex slave by the terror group eventually managed to escape and later resettled as a refugee in Germany after the harrowing ordeal.

But two years after her escape, she unexpectedly encountered her ISIS kidnapper while walking the streets of Stuttgart, Germany. The man she identified as Abu Hamam was living in Germany as a free man, and the police did nothing.

The Daily Mail reports the following of the Kurdish Yezidi woman Ashwaq Ta’lo’s testimony relating the shock encounter:

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 refugeeThe Times reports.
