An American adventurer, Mykhailo Viktorovych Polyakov, was arrested for illegally entering North Sentinel Island, home to an uncontacted tribe. Polyakov, who sought thrill and adventure, recorded his landing on the island using a GoPro camera, violating both local and national laws.
Fun fact; North Sentinel Island is protected by India, and if anybody goes there and gets killed, the Sentinelese will not be prosecuted.
