Attorney General's Office Raids Offices and Home of Samin Tan in Mining Corruption Case
The Attorney General’s Office (AGO) carried out searches at 14 locations related to the investigation of an alleged corruption case in the management of mining operations by PT AKT in Murung Raya Regency, Central Kalimantan. The searches were conducted in several regions, including DKI Jakarta, Central Kalimantan, and South Kalimantan.
Head of the AGO’s Legal Information Centre, Anang Supriatna, explained that most of the search sites were in Jakarta.
He stated that in DKI Jakarta, there were 10 locations searched, including the office of PT AKT, the office of PT MCM affiliated with PT AKT and suspect Samin Tan, Samin Tan’s residence, and several witnesses’ residences.
Meanwhile, in Central Kalimantan, searches were conducted at three locations: the PT AKT office, the KSOP office, and the office of mining contractor PT ARTH. In South Kalimantan, one location searched was the PT MCM office.
“From the results of the searches and seizures, several pieces of evidence have been collected so far, including documents, electronic evidence, as well as heavy equipment at the mining site and vehicles,” he said on Monday (30/3).
Currently, investigators are continuing to probe the possible involvement of other parties, including state officials in the case.
“Clearly, investigators are currently examining the involvement of parties, whether officials or affiliated parties suspected to be connected to this case,” he said.
In addition to focusing on criminal aspects, the AGO is also paying attention to efforts to recover state losses through asset tracing.
“These search and seizure activities are aimed at asset tracing for assets suspected to be related to or derived from the crime,” he said.
Previously, the AGO had named a suspect with initials ST or Samin Tan, who is the manager or beneficial owner of PT AKT. The company is known to have operated illegally from 2017 to 2025.
Director of Investigations at the Deputy Attorney General for Special Crimes, Syarief Sulaeman Nahdi, explained that PT AKT’s mining business permit had been revoked since 2017. However, mining activities continued.
“PT AKT continued to carry out mining and illegal and unlawful sales of mining products until 2025,” he said.
He added that suspect ST, through PT AKT and its affiliated companies, is alleged to have continued mining activities and coal sales using invalid permits, even collaborating with certain parties.
Nevertheless, the AGO has not detailed the identities of the state officials suspected of being involved in the mining oversight.
