Greta Thunberg’s pattern of joining high-profile protests that draw law-enforcement scrutiny continues to shape trader views on arrest probabilities. On October 7, 2026, she participated in a pro-Palestinian demonstration in Berlin’s Kreuzberg district marking the anniversary of the 2023 Hamas attacks; police halted the event after clashes, made over 30 arrests for banned symbols, and cited public-safety violations, though reports did not confirm her detention. Similar activism produced earlier detentions, including a July 2026 sit-in at Rheinmetall offices in Germany and a December 2025 London incident under the Terrorism Act. Her sustained involvement in climate and Palestine-linked actions, often involving blockades or restricted symbols, keeps the likelihood of future encounters elevated through year-end resolution windows.
