Indonesian Police in Jayapura, the provincial capital of Papua, have taken control of the Kingmi Synod church Office.
The Institute for Papuan Advocacy & Human Rights quotes sources from within the christian Church's community in Jayapura.
They say members of the Church, including Rev Zebelum Karubaba, the chair of the Kingmi Papuan Synod, are attempting to negotiate with Police to relinquish control.
200 of the Kingmi congregation have held a peaceful demonstration near the church.
It was expected that they would remain there all day and go home at night and then return in the morning.
No one has been arrested.
The Police presence at the demonstration was about 50 police - both Brimob paramilitary police and normal police) and these were outside the Synod office.
There is speculation that the Police action is a response to Kingmi church members activity in human rights campaigning.
