Attorney General's Office Raids Two Port Offices in Kalimantan in Samin Tan Case
The Attorney General’s Office (Kejagung) has once again conducted searches related to alleged corruption in the mining sector involving businessman Samin Tan. Investigators raided the Harbourmaster and Port Authority Offices (KSOP) in South Kalimantan and Central Kalimantan.
“Indeed (there were searches) in South Kalimantan and Central Kalimantan, specifically in Banjarmasin and Palangkaraya,” said the Director of Investigation for the Deputy Attorney General for Special Crimes (Jampidsus), Syarief Sulaeman Nahdi, when asked for confirmation on Wednesday (1 April 2026).
The searches were carried out on Tuesday (31 March) from afternoon until evening. Syarief confirmed that the targeted locations were the KSOP offices in those respective areas.
“Yes, that’s correct, both are KSOP offices,” he said.
During the operation, investigators seized several pieces of evidence. These included documents related to shipping activities of companies affiliated with Samin Tan.
“What was seized were shipping documents related to the suspect’s company and electronic evidence (BBE),” Syarief revealed.
Syarief also confirmed that these documents are suspected to be connected to the export shipping activities of mining products linked to the Samin Tan case.
14 Locations Searched
Previously, investigators had also searched 14 locations related to the alleged corruption case in the coal mining sector of PT Asmin Koalindo Tuhup (AKT). From those searches, Kejagung seized various pieces of evidence, including documents, vehicles, cash in US dollars worth around Rp 1 billion, and heavy equipment.
Of the total 14 locations searched, 10 were in the DKI Jakarta and West Java regions. These locations included offices of companies affiliated with the suspect, private residences, and homes of several witnesses.
“There are at the PT AKT office, at the PT MCM office affiliated with PT AKT or suspect ST, the residence of suspect ST and several witnesses,” said the Head of Public Relations for the Attorney General’s Office, Anang Supriatna, to reporters at the Public Relations building of Kejagung in South Jakarta on Monday (30 March).
In addition, investigators searched three locations in Central Kalimantan, including company offices, KSOP (Harbourmaster and Port Authority Office), and the office of mining contractor PT ARTH. Meanwhile, one other location was in South Kalimantan at the PT MCM office.
In this case, Samin Tan is named as the beneficial owner of PT AKT, a coal mining company that previously operated under a coal mining business contract agreement (PKP2B). However, the company’s permit was revoked in 2017.
Despite the permit revocation, PT AKT is alleged to have continued illegal mining and coal sales activities until 2025. Furthermore, these activities are suspected to have been carried out by violating permits and collaborating with rogue state officials responsible for supervision in the mining sector.
Kejagung has indicated the involvement of state officials in this case. However, to date, no officials have been named as suspects.
