Palu – A police station in Morowali regency, Central Sulawesi, became the target of stoning and Molotov cocktails by residents, in an attack allegedly linked to last year's deadly incident involving an offshore drilling company.

No fatalities or injuries were reported from the acts of around 20 people on the Mamosalato police station.

"They stoned the building but the bombs were targeted only at the office's fence," Central Sulawesi Police chief Brig. Gen. Dewa Parsana said on Wednesday when asked for confirmation by The Jakarta Post.

He said they could not confirm the motive behind the attack but speculated that it was related to a deadly offshore incident in which two were killed when a group of people launched a violent protest at Pertamina-Medco E&P Tomori in August last year, demanding Corporate Social Responsibility (CSR) funds.
