People living near a chimpanzee research center in Guinea attacked the facility on Friday after a woman said one of the animals had killed her infant, center managers said.
An angry mob ransacked the building, destroying and setting fire to equipment including drones, computers and more than 200 documents, center managers said.
Eyewitnesses said the crowd reacted to the news that the mutilated body of an infant had been found nearly two miles from the Nimba Mountains Nature Reserve, a UNESCO World Heritage Site.
The child’s mother, Seny Zogba, told Reuters she was working in a cassava field when a chimpanzee came up from behind, bit her and dragged her baby into the forest.
Local ecologist Alidjiou Sylla said the dwindling supply of food in the reserve forced the animals to leave the protected area more often, increasing the likelihood of attacks.
The research center said it had recorded six chimpanzee attacks on humans in the reserve since the beginning of the year.
The forests of Guinea, Liberia and Sierra Leone in West Africa are home to the largest population of the critically endangered western chimpanzee, which is estimated to have declined by 80% between 1990 and 2014, according to the International Union for Conservation of Nature.
There are only seven left in Guinea’s Bossou Forest, which forms part of the Nimba Mountains Nature Reserve, and which is close to subsistence farming communities in the Nzerekore region.
Chimpanzees are respected in Guinea and are traditionally given gifts of food, prompting some to venture out of the protected area into human settlements, where they can sometimes attack.
The Nimba Mountains are also home to one of Guinea’s largest iron ore reserves, which has raised concerns among environmentalists about the impact of mining on chimpanzees.
