Jakarta's notorious Betawi Brotherhood Forum (FBR) clashed with rivals Pemuda Pancasila in a deadly turf brawl in Kebayoran Baru, South Jakarta, early Sunday morning.
Sunday's violence began after members of a local chapter of the national PP reportedly saw FBR members removing PP banners hung along Jalan Barito, Jakarta Police spokesman Sr. Comr. Rikwanto said. The PP attacked the rival group, fatally stabbing 44-year-old FBR member Ramlan in the brawl.
Ramlan was badly beaten in the attack and suffered stab wounds to his head, back and chest, Rikwanto said.
"The victim [of Sunday's incident] wore a black FBR shirt," he said. "The victim had been badly assaulted, which led to his death."
Jakarta Police conducted a sweep of the nearby Ayodya Park, a PP hangout, targeting members of the violent "mass organization." Officers met with representatives from both groups in an attempt to quell any remaining tensions.
"We've coordinated with the groups PP and FBR to prevent a widespread conflict," Rikwanto said.
It is unclear if any arrests were made following Ramlan's death.
Sunday's brawl was the third reported clash between the rival groups this year. The FBR allegedly ambushed PP members in Gandaria, South Jakarta, in late February. Police arrested three FBR members following that incident.
The South Jakarta attack was reportedly revenge for similar brawls in Jakarta and Depok, West Java, that occurred in the wake of the murder of an FBR member in Ciputat, Tangerang.
The PP and FBR are both known for their thuggish behavior and use of violence to run street-level extortion rackets.
