Police in the Indonesian region of Papua have detained five people for allegedly beating to death the leader of the Beoga tribe in Timika on Friday.
Papua Police Chief, Bagus Eko Danto, says the mob became enraged when Joker Japugao, the head of the tribe, made disparaging comments about the Moni and other tribes.
The Jakarta Post says there have been reports of planned retaliation but Chief Danto says the situation is under control.
But he says thousands of police and Indonesian Armed Forces personnel had been deployed to safeguard the town since Friday night.
They were also guarding the hospital to prevent more clashes.
