Investigators of the Attorney General's Office (AGO) have named two more suspects in the corruption case related to alleged mismanagement of crude oil and refinery products of State energy company PT Pertamina. 

The two suspects are Maya Kusmaya, Director of Central Marketing and Commerce at Pertamina Patra Niaga, a commercial and trading subholding of Pertamina, and Edward Corne, Vice President for Trading at Pertamina Patra Niaga. 

"Investigators have found sufficient evidence that the two are suspected of committing a crime together with the seven suspects that we have previously named," Director of Investigation at the Office of Junior Attorney General for Special Crimes, Abdul Qohar, told a press conference in Jakarta on Wednesday evening, February 26, 2025. 

The two suspects were then sent to the Salemba Prison in Central Jakarta for detention for the next 20 days.

The arrest of two more suspects adds to the number of seven suspects already detained over the Pertamina graft case.

The seven suspects are Riva Siahaan, President Director of PT Pertamina Patra Niaga; Sani Dinar Saifuddin, Director of Feedstock and Product Optimization at Pertamina’s refinery and petrochemical arm PT Kilang Pertamina Internasional; Yoko Firnandi, President Director of Pertamina’s shipping subholding PT Pertamina International Shipping.

Exploring Riza Chalid's involvement

The AGO is also exploring the potential involvement of oil trader Mohammad Riza Chalid in this case. Riza's son, Muhammad Kerry Andrianto Riza (MKAR), has already been named a suspect.

The AGO has even searched Riza's house on Jalan Jenggala II in Kebayoran Baru, South Jakarta and confiscated a number of pieces of evidence there. 

"That's what we want to study and develop. Why were there documents in the person's [Riza Chalid] house?Was he involved? What was his role? And so on. That's what investigators will look for the common thread," AGO Spokesman, Harli Siregar, said. 

Harli cited that investigators found important documents and hundreds of millions of rupiah in cash during the search at Riza Chalid's house. Investigators will analyze the evidence to determine whether there is involvement of other parties in this case. 

"I think the possibility of naming new suspects in this case is still open, considering the facts and evidence that have been collected," he said. 

Harli revealed that investigators found Rp833 million (US$50,878) and US$1,500 in cash during the search at Riza Chalid’s residence, which was used as an office. 

He also revealed that investigators found 34 large folders various files related to crude oil imports, including shipping documents. 

In addition, investigators also confiscated 89 bundles of documents and two CPUs (central processing units) that are suspected of storing electronic data related to this case. 

“AGO investigators are still analyzing the confiscated evidence to further uncover potential involvement of other parties in this case,” Harli said.
