Overview

• An anonymous UK internet user reported online content on 4 September to the Met’s Counter Terrorism Internet Referral Unit warning of an imminent attack in Ukraine.
• The Met immediately passed the alert to Europol, which notified Ukrainian authorities who arrested a 15-year-old at a school in Zakarpattia the next day.
• Ukrainian officials said the student was livestreaming as he tried to enter the school and that police seized a rucksack containing knives.
• The Ukrainian Ministry of Internal Affairs shared an image showing the knife, phone, and bag taken during the detention, confirming the items recovered.
• Commander Dominic Murphy said the swift cross-border response likely saved lives and urged the public to report suspicious online material via gov.uk/ACT.
