A woman has described her struggle with post-traumatic stress disorder after she was sedated with drugged strawberries and then held prisoner in a bunker for six days by a doctor likened to a “Swedish Josef Fritzl”.

Appearing under the pseudonym “Isabel Eriksson”, the 39-year-old former escort said in a Swedish documentary series that she felt “panicked” and “powerless” as she was kidnapped from Stockholm and locked away on a farm 350 miles away to the south in 2015.

Her captor, Martin Trenneborg, now 47, admitted to her abduction several months later and was sentenced to ten years in prison.
