Reports from Indonesia indicated as many as 90 Papuans were taken in by police in Timika after holding a public event to support human rights. A lawyer representing Papuans, Veronica Koman, said another 41 were arrested in Merauke.
The pro-independence West Papua National Committee, or KNPB, has issued a statement saying its activists were among those taken in by police in Timika.
Offices of the KNPB's secretariat around Papua region were raided by police on 1 December, the anniversary of 1961's West Papuan declaration of independence. Police arrested around 500 people for marking the anniversary last week.
