Overview

• The Kammergericht convicted the youth of preparing a serious state‑endangering act and supporting a terrorist violent act abroad.
• Judges said the then‑14‑year‑old, radicalized online as an IS supporter, sent a bomb‑making video, translated instructions, and brokered contact to an IS member for the Austrian suspect.
• The court reported a comprehensive confession during the juvenile proceeding, and imposed a one‑and‑a‑half‑year sentence suspended on probation in line with the federal prosecutor’s request.
• Austrian authorities uncovered the plan before any attack occurred; three Vienna shows were canceled and the Austrian suspect was arrested on August 7, 2024.
• The judgment is not yet legally binding, and Austrian investigators continue to evaluate seized data in the related case against the main suspect.
