Attorney General's Office Raids Several Locations in Central Kalimantan and Jakarta in Samin Tan Case
The Attorney General’s Office (Kejagung) has named businessman Samin Tan as a suspect in an alleged corruption case in the coal mining sector at PT Asmin Koalindo Tuhup (AKT). In developments, investigators have also raided several locations related to the case.
The Director of Investigation for the Deputy Attorney General for Special Crimes (Jampidsus) at Kejagung, Syarief Sulaeman Nahdi, stated that Tan’s designation as a suspect followed the investigators obtaining sufficient evidence. This evidence was gathered through a series of witness examinations and searches at numerous locations.
The searches were conducted in West Java, South Kalimantan (Kalsel), DKI Jakarta, and Central Kalimantan (Kalteng). As of now, the search process is still ongoing, particularly in Central Kalimantan and South Kalimantan.
“Searches were carried out in several regions, namely West Java, South Kalimantan, DKI Jakarta, and Central Kalimantan,” said Syarief during a press conference at Kejagung in South Jakarta on Friday evening (27/3/2026).
“And it should be noted that the searches are still ongoing at present, especially in the Central Kalimantan and South Kalimantan areas,” he continued.
Additionally, investigators raided several affiliated companies, including PT Borneo Lumbung Energi & Metal (BLEM), which is said to have connections to Samin Tan.
“Regarding the searches, they are indeed still ongoing. They are ongoing in several places in South Kalimantan, Central Kalimantan, Jakarta, and West Java. The company mentioned earlier (PT BLEM) is indeed an affiliated company,” Syarief responded to reporters’ questions.
In the construction of this case, Samin Tan is identified as the beneficial owner of PT AKT, a coal mining company that previously operated under a Coal Mining Business Work Agreement (PKP2B). However, the company’s licence was revoked in 2017.
Despite the revocation of the licence, PT AKT is alleged to have continued mining and selling coal illegally until 2025.
“After the revocation, PT AKT continued to carry out mining and the sale of mining products unlawfully and against the law until 2025,” he revealed.
Furthermore, these activities are suspected to have been conducted by violating invalid permits and collaborating with rogue state officials responsible for supervision in the mining sector.
“Thus causing harm to the state finances or the national economy,” Syarief added.
Kejagung indicated the involvement of state officials in this case. However, as of now, no individuals from those elements have been named as suspects.
“I have already stated that in this case, there is collaboration with state officials tasked with supervising the mine. As for who the state officials are, we will convey that later,” Syarief explained.
He noted that the element of collaboration with state officials forms the basis for classifying this case as a corruption offence.
In this case, Samin Tan is charged with violating Articles 603 and 604 of the Criminal Code. He is now detained for the next 20 days at the Salemba Branch Detention House of the Attorney General’s Office.
