VIENNA—Austrian investigators have arrested a 14-year-old who was planning an attack at a railway station in Vienna and found material that suggested he supported the ISIS terrorist group, authorities said Wednesday.
The Interior Ministry said that the boy, an Austrian with Turkish roots, was arrested in the capital on Feb. 10 and had been radicalized online. The arrest was triggered by tips to Austrian intelligence that a supporter of ISIS had posted stories and videos with Islamic extremist content on several TikTok profiles.
