A 24-year-old American tourist, Mykhailo Viktorovych Polyakov, has been detained in India for allegedly entering North Sentinel Island, home to the isolated Sentinelese tribe.
Polyakov left a can of Coke and a coconut as "offerings" and collected sand samples while filming his visit, police said.
Access to the island is strictly prohibited for two reasons: to protect the Indigenous people from diseases and preserve their way of life.
This incident follows the 2018 killing of American missionary John Allen Chau by the Sentinelese tribe.
The navy has enforced a three-mile buffer zone around the island to prevent unauthorised entry.
