15-year-old Natascha Colding-Olsen planned to build a bomb to blow up two schools in Denmark: Sydskolen in Fårevejle (near
Holbæk), which she previously attended, and
Carolineskolen, a Jewish school in
Copenhagen. The plotter was 17 at the time of her trial. An American captain from Iraq warned Denmark, which led to detention of the girl and a 24-year-old Turkish man. The plotter, a recent convert to Islam, wrote on her Facebook page of her desire to help convert more Danish people to Islam and joined a
Facebook page for
ISIS supporters. Colding-Olsen was described as having undergone a rapid transformation, changing within a few months from a teenager interested in clothes and boys, into a young woman interested in fighting a holy war. but in early 2017, when 25 years old, he received a prison sentence, lost his
Danish citizenship (he had been a
dual national of Turkey and Denmark) and was banned for life from visiting Denmark after being convicted of joining the terror organization ISIS during trips to Syria. He was only the second person to lose his Danish citizenship due to terror-related charges. == History ==
