Indonesian police and military officers in Papua have raided the headquarters of the separatist group Free Papua Movement in Papua's Pantura Yapen district.
A police spokesman, senior commissioner Sulistyo Pudjo Hartono, has told the Jakarta Globe the separatist group has long provoked fear among local residents, threatening individuals who did not meet their demands.
He says a special team from Yapen Islands district police approached the headquarters and an exchange of gunfire took place for about 20 minutes.
He says members of the movement managed to escape and fled into the forest, leaving police to seize 20 rounds of ammunition, five firearms, a motorbike and a camouflage uniform found on the premises.
Senior commissioner Hartono says the police are taking steps to anticipate any act of revenge, by deploying more troops at the Angkasera district police station.
