Mykhailo Viktorovych Polyakov, 24, set foot on the restricted territory of North Sentinel – part of India’s Andaman Islands – in an attempt to meet the Sentinelese people, who are believed to number only about 150.

“The American citizen was presented before the local court after his arrest and is now on a three-day remand for further interrogation,” the Andaman and Nicobar Islands police chief, HGS Dhaliwal, told AFP.
