The National Police are investigating two foreign companies for alleged involvement in causing land and forest fires in Central and West Kalimantan.
National Police spokesperson Agus Rianto identified the two companies as Chinese-owned PT ASP and Australian-owned PT KAL.
"Two foreign investors are currently under investigation, namely, PT ASP [in Central Kalimantan] and PT KAL [in West Kalimantan]," Agus said on Sunday as quoted by kompas.com.
The government has recorded a total of 42 million hectares of land on fire in Sumatra and Kalimantan while the police are currently working on 238 cases.
Agus added that of the 238 cases, 191 involved individual perpetrators while 47 involved corporations.
"Two hundred and five people have been named suspects in individual cases while 11 people have been named suspects in the corporate cases. Seventy-two people have been detained," he said.
A prolonged dry season and arid peatland have resulted in forest fires, which has led to spreading haze in Sumatra, Kalimantan and Singapore as well as parts of Malaysia.
