The loggers now face prison terms of three to six years if prosecuted. Survival International did not specify how many loggers were arrested during the raid, which was carried out by Peru's Department for Protected Areas, police and park guards.
According to Survival International, sightings of the uncontacted tribe have risen in recent months, "with many blaming illegal loggers for pushing the tribe out of their forest homes."
FENAMAD, an indigenous peoples advocacy group in Peru, is working on establishing a guard post near the Mashco-Piro tribe's current settlement to protect the tribe from intruders.
"A week ago very few people had heard of the uncontacted Mashco-Piro," Survival International's Director Stephen Corry said. "Now their faces are recognized worldwide, and the dangers facing them are known. Catching illegal loggers red-handed clearly shows the very real threats facing uncontacted tribes in Peru."
