A 24-year-old American YouTuber who visited an off-limits island in the Indian ocean to try to make contact with an isolated tribe faces charges with a possible sentence of up to five years in prison. Mykhailo Viktorovych Polyakov, from Scottsdale, Arizona, was arrested on 31 March, two days after he set foot on the restricted territory of North Sentinel Island — part of India’s Andaman and Nicobar Islands — in a bid to meet people from the reclusive Sentinelese tribe, according to police.

Polyakov was placed in judicial custody for 14 days and is scheduled to appear in court on April 17th. He faces up to five years in prison and a fine. Indian authorities informed the US Embassy about the case. Visitors are prohibited from traveling within three miles of the island, which has been isolated for thousands of years.

The people utilize spears, bows, and arrows to hunt the animals that wander the small, densely forested island. They are deeply wary of outsiders and attack anyone who lands on their shores.
