Natascha Colding-Olsen, who is commonly known in Denmark as "The Kundby Girl," was found guilty of plotting attacks against her own Sydskolen school in Fårevejle, as well as the Jewish school Carolineskolen in Copenhagen and sentenced to eight years, Danish Radio reported.
The girl had procured explosive precursors and had been searching for manuals on bomb-making, the court found. She was also planning a test explosion, which constituted solid grounds for terrorism charges.
The girl's profile on the social media indicated that she was a member of a Facebook group for Danish supporters of Hizb ut-Tahrir, a radical Islamist organization openly supporting the establishment of a hardline caliphate. Hizb ut-Tahrir was previously banned from using municipal premises in Denmark following a spate of controversies.
Defender Mette Grith Stage said she was disappointed, as he was hoping to get the girl cleared of the terrorism charges. Prosecutor Kristian Kirk, however, demanded indefinite custody, one of Denmark's toughest penalties.
The prosecution emphasized that the girl had a pronounced personality disorder and significant identity problems owing to her turbulent youth. She was also found guilty of inflicting bodily harm after stabbing a teacher at the closed institution Grenen with a shard of a broken mirror.
"The Forensic Council found she's dangerous. Quite unequivocally. Do you think she has given up her plans for terror? And how easy would it be for a radical Islamist to make her carry out a terrorist act? She is actually proud of being ‘The Kundby Girl,'" Prosecutor Kristian Kirk said.
Kirk emphasized that the girl was a likely "associate" that is "easy to manipulate," adding that she neither showed any signs of anger nor self-reflection.
In a letter to Danish TV-channel TV2, Colding-Olsen herself claimed she regretted the actions for which she was convicted. Among other things, because the punishment impeded her future plans.
"I was only a 15-year-old girl then, so the severity of it all was hard for me to see. Unfortunately, that mistake will pursue me the rest of my life now. For example, when I go out and have a job one day. I had the idea of becoming a paramedic ever since I was little, but I'd better say farewell to this hope," Natascha Colding-Olsen wrote to TV2.
