BRASILIA, Brazil (Associated Press) — A young man from an isolated Indigenous tribe who approached a riverine community in Brazil’s Amazon returned voluntarily to his people less than 24 hours later, Brazilian authorities said.
The encounter occurred around 7 p.m. local time Wednesday in Bela Rosa, a community along the Purus River in the southwestern Amazon.
Footage obtained by The Associated Press shows him barefoot and wearing a small loincloth, seemingly calm and in good health as he carried two logs.
