Indian police have arrested a 24-year-old American Youtuber who visited an off-limits island in the Indian ocean to try to establish contact with an isolated tribe known for attacking intruders.

Mykhailo Viktorovych Polyakov, of Scottsdale, Arizona, left a Diet Coke and a coconut for the reclusive Sentinelese people, police said.

A 24-year-old American man went to a far-flung island in hopes of filming an encounter with the Sentinelese, the Indian authorities said. It is illegal to make contact with the tribe.
