Jakarta – Security was heightened in the town of Kwamki Baru, Timika, on Friday after two groups of local residents were caught in brawl, putting the city in fear of further violence.

The two groups used stones and arrows in the fight, which broke out on Thursday's afternoon, tempointeraktif.com reported Friday.

A number of police officers were seen firing warning shots to disperse the opposing sides. The brawl also forced police to reroute traffic to avoiding Jl. Trikora. Most stalls and stores in the neighborhood of Jl. Trikora were closed.

The strained tensions between two groups was allegedly triggered by an affair involving the Okto Kelabegme family and Kuk Nebegelen, the wife of Kemen Obagame.

The Obagame family demanded a fine of Rp 50 million (US$5,850) and three pigs, based on local traditions, but the Kelabegme family apparently failed to meet the demand.

"[The Obagame family] demanded Rp 50 million, but the other family only managed to collect Rp 17 million," said a resident, Meno Imbir.
