Security officials believe there are at least ten, and possibly more, radical Islamist “high-risk individuals” in Austria who could attack at any time. In addition to the 17-year-old from the main railway station, an IS supporter of the same age who was recently deemed exceptionally dangerous was sentenced in January by the Vienna Criminal Court to 21 months of partial imprisonment for organizing a terrorist organisation. Showed IS propaganda material in his school. Sprayed IS symbols on a bridge pillar and carried out patrols with knives bearing IS symbols.
Just three months after his release, the young man is said to have resumed IS propaganda and along with a colleague shot a man sitting on a park bench in the thigh with an air rifle. In late November, he and his alleged accomplice will stand trial again for terrorist organization and attempted grievous bodily harm.
