Brazilian authorities say 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.

The young man from an Indigenous Amazonian tribe is receiving medical treatment, while authorities prepare to attempt communication with him.

In a rare encounter, a young man from an isolated Indigenous tribe approached a riverine community in Brazil’s Amazon, according to the country’s Indigenous affairs agency and local witnesses.

Reportedly, the villagers believed that the man from the uncontacted Indigenous Amazon tribe contacted them to ask for fire.

Meanwhile, Brazil’s Fundação Nacional dos Povos Indígenas (National Foundation of Indigenous Peoples, or Funai) estimates around 100 uncontacted Indigenous groups still live deep in the Amazon rainforest. But on February 12, a man from one of those communities decided to meet his neighbors.

A young man from an isolated indigenous tribe who approached a community in Brazil’s Amazon returned voluntarily to his people less than 24 hours later, Brazilian authorities said. The encounter occurred at around 7pm local time on Wednesday in Bela Rosa, a community along the Purus River in the south-western Amazon.
