Indonesian police have reportedly arrested more than a hundred members of the West Papua National Committee, or KNPB, in Jayapura.
The KNPB said 104 of its members were taken in to custody after police searched a student dormitory in the Papua provincial capital.
A discussion to mark the tenth anniversary of the pro-independence organisation's inception had been about to take place.
The KNPB said the executive director the United Liberation Movement for West Papua Markus Haluk was also arrested.
