Veteran environmentalist Paul Watson, 73, was arrested in Greenland on an international warrant issued by Japan for his anti-whaling activities in the Antarctic years ago. The 73-year-old was detained by Danish police when his ship docked in Nuuk to refuel, and he faces possible extradition to Japan. Watson's arrest is linked to a former Red Notice, which his foundation claims was reactivated for politically motivated reasons, coinciding with the launch of Japan's new whaling ship. The Captain Paul Watson Foundation has called for his release, arguing the warrant was confidentially maintained to facilitate his arrest. Watson, known for his direct action tactics against whaling vessels, has previously faced legal challenges from both Japan and Costa Rica. His case will be reviewed by a district court to determine if he will remain detained pending extradition decisions.
