Recent detentions of Greta Thunberg stem primarily from her participation in pro-Palestinian and climate protests. Israeli naval forces intercepted the Gaza-bound aid vessel Madleen on August 20, 2026, detaining her and other activists for attempting to breach the blockade, with plans for deportation following. In December 2025, London police arrested her under the Terrorism Act during a demonstration supporting banned group Palestine Action. A separate London court acquitted her on August 22, 2026, in a prior public-order case tied to blocking an oil and gas conference. Ongoing activism, including a major Stockholm climate rally on August 23, 2026, ahead of Sweden’s election, sustains the potential for further encounters with law enforcement across jurisdictions.

Temporary holding at a detention facility while awaiting a judge’s decision on whether to grant a detention warrant qualifies, so long as they are held by law enforcement in an official capacity during that time.
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.
