The investigation team of the Deputy Attorney General for Special Crimes (Jampidsus) of the Attorney General's Office continues to investigate allegations of corruption at Pertamina. On Friday, March 21, 2025, investigators examined six witnesses, including the President Director of a beneficiary company suspected of being related to Riza Chalid's oil merchant family.

Five of the six witnesses came from Pertamina's subsidiary, ranging from PT Patra Niaga to PT Kilang Pertamina Internasional. Meanwhile, another witness came from the private sector who was suspected of enjoying the benefits of this scandal.

Those examined included IR, Pjs. VP Feedstock Management of PT Kilang Pertamina Internasional in September 2023; Alfian Nasution, President Director of PT Patra Niaga in 2021; and RW, VP Procurement and Asset Management of PT Pertamina International Shipping.
