Indonesian Police Arrest 72 Suspected of Starting Forest and Peatland Fires

JAKARTA — Indonesian police on Sunday arrested 72 people suspected of starting some of the recent forest and peatland fires that have blanketed parts of the country in a choking haze and sent dense smoke into neighboring Malaysia.

The arrests come as Indonesia battles fires driven by an intensifying El Niño pattern and a prolonged dry season, according to the National Disaster Management Agency (BNPB). Forest and land fires are a recurring problem in the country and often strain relations with neighboring countries.

Mohammad Irhamni, director of special crimes at the National Police’s Criminal Investigation Agency, said plantation owners and traditional farmers often start fires to clear land for farming. The suspects are being investigated in connection with 89 forest and land fire cases across five provinces on the island of Borneo and four on Sumatra.

Most of the suspects are accused of deliberately burning land to clear areas for plantations at lower cost. Investigators are also tracing financial records to determine whether companies financed or ordered the land clearing, signaling the probe could expand beyond those arrested.

“We will not stop at the perpetrators on the ground,” Irhamni told a news conference in Jakarta. “We will determine who benefited from these activities and who was ultimately behind them.”

The suspects face charges carrying penalties ranging from hefty fines to prison terms of up to 15 years.

President Visits Fire Zones, Vows Accountability

President Prabowo Subianto flew on Saturday to Central Kalimantan province, where more than 7,600 hectares (18,700 acres) have burned, to encourage authorities to bring the haze under control. He promised government resources, including helicopters and water pumps, and vowed to hold accountable any companies found to have contributed to the fires.

“I hope we can control this soon,” Prabowo said during the visit. “We have experienced worse forest and land fires in the past, and we were able to overcome them.”

Prasetyo Hadi, head of the State Secretariat, said at least four companies in West Kalimantan province are under investigation for allegedly using fire to clear land. If proven to have intentionally set fires, the companies could face sanctions including revocation of their operating permits.

Hotspots and Haze Spread Across the Region

Smoke from the fires on Sunday blanketed parts of Borneo, the world’s third-largest island shared by Indonesia, Malaysia, and Brunei. Indonesia administers about three-quarters of the island.

The Environment Ministry recorded more than 3,700 hotspots on Borneo on Sunday. BNPB chief Suharyanto said fire activity had increased in West, Central, and South Kalimantan provinces, where many blazes worsen due to peatlands.

“Fires that appear extinguished on the surface may still contain embers underneath,” Suharyanto said, stressing that sufficient rainfall is crucial to rewet the peat and fully suppress the fires.

South Sumatra had more than 1,700 hotspots detected on Sunday, with haze reducing visibility in some areas to only 10 meters (33 feet).

Cloud-seeding resumed over Kalimantan on Sunday, with 30 helicopters conducting water-bombing and aerial patrol missions, and another 22 helicopters covering Sumatra — a total of 52 helicopters deployed.

Cross-Border Impact

In Malaysia’s Sarawak state, one district recorded very unhealthy air quality on Friday while eight others posted unhealthy readings. Nearly 600 schools in Sarawak were closed, affecting about 200,000 students, according to the Sarawak government.

Officials say the fires are a reminder of the region’s vulnerability to climate-driven disasters, as Indonesia and its neighbors brace for the ongoing El Niño season.
