A gang of unidentified men has raided the Jakarta office of Els-Ham, the Papuan human rights group which has accused the Indonesian military of being involved in a fatal ambush near the Freeport mine two months ago.
Els-Ham's Albert Rumbekwan says five men broke into the office and seized documents and computer disks holding information about the ambush.
Mr Rumbekwan says papers on last November's murder of Papuan indendence leader, Theys Eluay, were also seized.
He suspects the military, but a spokesperson for the Indonesian Armed Forces is denying all knowledge of the incident.
