The Corruption Eradication Commission (KPK) has officially designated PT Loco Montrado (LCM) as a corporate suspect. The company is allegedly implicated in a corruption case concerning a metal anode processing cooperation with the state-owned mining giant, PT Antam Tbk. KPK spokesperson Budi Prasetyo confirmed that PT LCM has been a suspect since August 2025. “KPK has designated PT LCM as a corporate suspect in the case concerning the metal anode processing cooperation with PT Antam,” Budi informed reporters on Tuesday (October 14). He did not, however, elaborate on the specific details or construction of the case.
Antam Metal Anode Processing Case
This corporate designation follows a protracted anti-corruption investigation that had previously implicated Siman Bahar, the CEO of PT Loco Montrado. The KPK initially suspected corruption linked to a cooperation agreement for metal anode processing between PT Antam and PT Loco Montrado, dating back to 2017. However, Siman Bahar successfully challenged his initial suspect status, winning a pre-trial motion filed at the South Jakarta District Court, where the judge ruled his designation invalid and without legal force.
Despite the earlier setback, the KPK reignited its efforts, re-designating Siman Bahar as a suspect in a similar case on June 6, 2023. The anti-corruption investigation into these serious allegations remains ongoing. The latest development in this complex case is the formal naming of PT Loco Montrado as a corporate suspect, broadening the scope of the legal proceedings.
Witness Examination
As part of the continuing probe, the KPK is actively questioning various witnesses. Notably, Arie Prabowo Ariotedjo, the former CEO of PT Antam, was interrogated on Tuesday (October 7). He was questioned extensively regarding alleged fraud within the cooperation process between PT LCM and PT Antam. Arie Prabowo has yet to issue a statement regarding this specific examination. It is important to note that Arie Prabowo had previously provided testimony in this very case on June 6, 2023. His insights were crucial because the initial allegations of corruption were reported by PT Antam itself during his tenure as CEO. His testimony was sought again following Siman Bahar’s re-designation as a suspect by the KPK.
Explaining the necessity of his re-examination, Arie Prabowo stated, “They (KPK) only questioned us again because, according to them, a new official report needed to be made. The original report was voided because the KPK lost in the pre-trial motion. Therefore, this official report must be repeated. Firstly, we were likely the reporters, and secondly, all chronological data is available, so it could be done quickly.”
The individuals and entities implicated in this significant corporate corruption case are being charged under Article 2 Paragraph 1 or Article 3 of the Anti-Corruption Law (UU Tipikor) in conjunction with Article 55 Paragraph 1 Subsection 1 of the Criminal Code (KUHP), highlighting the serious nature of the alleged offenses.
