A video released by Brazil's National Indian Foundation, or FUNAI, shows an an isolated Indian tribe's first contact with civilization in Acre, a state on the border with Peru, and how the Indians interact with a nearby indigenous community.

Members of the tribe were first spotted on June 27, when FUNAI personnel out fishing saw two Indians who had dropped a basket of lemons on the banks of the Envira River.

The video, which was released on Tuesday, shows the first direct contact with the tribe on June 29.

Ashaninka Indians from Simpatia, a village on the banks of the Envira River, who receive medical care from the agency helped in making contact with the new tribe, the FUNAI said.

The video shows the Ashaninkas making contact with some members of the isolated tribe, who make signs that they are hungry and are given bananas.

The meeting between the Indian groups was not friendly, with the new tribe, armed with bows and arrows, looting the Ashaninka dwellings and stealing hatchets and clothing, the FUNAI told Efe.

It is still not clear why the tribe contacted the Ashaninkas, but it may be that the isolated group came under pressure from Peruvian loggers, FUNAI anthropologists said.

The previously unknown tribe had a shotgun that may have been stolen from a logger or abandoned by an outsider.
