Greta Thunberg’s activism linking climate issues with opposition to arms production and the Gaza conflict has driven repeated police interventions at protests. In December 2025, City of London Police detained her under the UK Terrorism Act for displaying a placard supporting the proscribed group Palestine Action during a demonstration outside an insurance firm; she was released on bail. Berlin police arrested her in July 2026 at a blockade targeting Rheinmetall’s offices over weapons shipments. Earlier actions produced charges in Sweden and Denmark, with a Copenhagen trespassing verdict expected in 2026. Traders monitor her protest schedule and any new flotilla plans, as these events frequently trigger detentions by local authorities under public-order or counter-terrorism statutes.

A qualifying arrest/detention includes:
* Being taken into physical custody by law enforcement authorities (including federal, state, local, military, or international law enforcement)
* Voluntarily surrendering to law enforcement authorities in response to an arrest warrant
* Being formally booked or processed following detention
* Being handcuffed by a state authority and taken to a police station
* Surrendering at a police station or courthouse with their attorney
* Being placed under house arrest or electronic monitoring
The following scenarios will NOT qualify as an arrest/detention
* An arrest warrant being issued but not executed
* Being questioned or interviewed without arrest
* Being named in an indictment without arrest
The primary resolution source for this market will be official information from the arresting government and law enforcement; however, a consensus of credible reporting may also be used.
