Three Suspects in Samin Tan Mining Permit Corruption Case Immediately Detained at Cipinang Detention Centre
The Attorney General’s Office (AGO) has immediately detained three new suspects in the development of the alleged corruption case involving irregularities in business mining permits for PT Asmin Koalindo Tuhup (AKT) in Murung Raya Regency, Central Kalimantan.
Director of Investigation of the Deputy Attorney General for Special Crimes (Jampidsus) Syarief Sulaeman Nahdi stated that the three suspects have been detained for the next 20 days at Class I Cipinang Detention Centre in East Jakarta.
“The suspects are currently being held in detention for the next 20 days at Class I Cipinang Detention Centre,” said Syarief during a press conference at the AGO building in Jakarta on Thursday night (23/4/2026).
Syarief explained that the determination of the three as suspects is the result of the investigation’s development in the case that previously ensnared Samin Tan as the beneficial owner of PT AKT.
In this case, HS is alleged to have abused his authority by issuing shipping approvals for the transportation of coal that actually originated from PT AKT, but using invalid documents.
“The suspect also received monthly payments unlawfully from a company affiliated with suspect ST, who is the BO (beneficial owner) of PT AKT,” Syarief clarified.
“Thus, the suspect did not conduct checks on the verification result reports from the Ministry of Energy and Mineral Resources as a requirement for issuing the shipping order letter,” he continued.
These activities were carried out using documents from other companies without valid permits, including through companies affiliated with PT AKT.
Meanwhile, HZM played a role in manipulating coal laboratory test result documents or certificate of analysis (COA), as well as verification result reports.
“The suspect, as GM in the maritime and cargo sector, together with suspect ST and his affiliated companies, created Certificate of Analysis or COA documents for coal laboratory test results sourced from the mining area in the PKP2B region of PT AKT, which had been terminated,” he revealed.
Syarief added that HZM was initially uncooperative, skipping two investigator summonses before being forcibly brought in and designated as a suspect.
The three suspects are charged under Article 603 and Article 604 of the Corruption Eradication Law (Tipikor).
In the investigation process, the Jampidsus team also conducted searches at two KSOP offices, namely in South Kalimantan and Central Kalimantan.
The searches were carried out in Banjarmasin and Palangkaraya at the end of March 2026.
From these activities, investigators seized a number of shipping documents as well as electronic evidence related to the activities of the company and other related parties.
