The West Papua Liberation Army says it has torched the base camp of a logging company in Maybrat regency.
A faction of the pro-independence army has released photos of some of its members outside the burning premises of Indonesian company PT Bangun Katu Irian.
But police say the arson attack was done by an employee of the company, and that investigations are underway.
Local Papuan communities have protested against the activities of logging companies who they say are destroying traditional livelihoods without a social license.
Maybrat has been one of the focal points of armed conflict between the Liberation Army’s guerilla fighters and Indonesian security forces, with thousands of villagers displaced after violence escalated in September.
