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.

Andaman and Nicobar Islands police said Mykhailo Viktorovych Polyakov took an inflatable boat to North Sentinel Island with a Diet Coke and a coconut as offerings.

A U.S. tourist sneaked onto a highly restricted island carrying a coconut and a can of Diet Coke to a tribe untouched by the modern world, police said.
