Medan Chief Prosecutor Implicated in Alleged Extortion of Corruption Defendant in Kupang

Two prosecutors are alleged to have been involved in extorting defendant Hironimus Sonbay alias Roni in a school renovation project in Kupang City and Kupang Regency. The two are Ridwan Sujana Angsar and Noven Verderikus Bulan.

Ridwan currently serves as the Chief Prosecutor of Medan, North Sumatra. Meanwhile, Noven Bulan is assigned to the NTT Attorney General’s Office. The alleged extortion was revealed in the reading of the plea note or defence by Roni’s lawyer, Fransisco Bessie, during the trial at the Kupang Corruption Court (PN Tipikor Kupang) on Tuesday night (28/4/2026).

The trial was presided over by Chief Judge I Nyoman Agus Hermawan with members Raden Haris Prasetyo and Bibik Nurudduja. The defendants in this case are Roni, Didik, and Hendro Ndolu.

“From the beginning, this case has been too forced because the defendant has already paid a lot of money to certain prosecutors, namely Ridwan Sujana Angsar who at that time served as Chief Prosecutor of Oelamasi, Kupang Regency,” said Fransisco while reading the plea note on Monday.

Fransisco revealed that Ridwan received Rp 140 million in 2022, paid in stages. The first payment of Rp 50 million was made at Hotel Sasando in Kupang City. The second payment of Rp 50 million was handed over through a person named Gusty Pisdon at his home in Sikumana Subdistrict, Kupang City.

Subsequently, Ridwan met Roni at Hotel Naka. In that meeting, Ridwan claimed to have received only Rp 40 million. Roni then called Gusty to inquire about the remaining money.

Gusty admitted to giving Rp 10 million to Benfrid Foeh, who was later identified as a prosecutor. Ridwan is also said to have met defendant Didik at Oepoi Sports Hall in Kupang City and demanded an additional Rp 50 million.

“At that time, the prosecutor named Ridwan Sujana Angsar said that he did not want to know, you two (Roni and Didik) must prepare Rp 50 million, tomorrow it must be handed over to me because there is a need in Jakarta,” said Fransisco.

Since Didik did not have the money, Roni covered the demand and delivered Rp 50 million to the gate of the NTT Attorney General’s Office. The money was received by Ridwan’s personal driver and witnessed by Roni’s driver.

Besides Ridwan, Fransisco mentioned Noven Bulan, who at the time served as Head of Intelligence at the Oelamasi Prosecutor’s Office, is also alleged to have extorted Roni for around Rp 175 million. Of that amount, Rp 150 million was used, while the rest was said to pay an expert from Kupang State Polytechnic.

Roni is also said to have handed over Rp 500 million to commitment-making official (PPK) Hendro Ndolu, paid in two stages: Rp 200 million and Rp 30 million.

“Thus, all that evidence has been officially submitted on 21 April 2026 during the trial and directly received by the Panel of Judges examining and handling the case,” Fransisco explained.

According to Fransisco, the evidence is strengthened by the testimony of NTT criminal law expert Mikhael Feka when examined as an expert witness.

Corruption Charges in School Project

In the indictment, Roni is charged with corruption in the rehabilitation and renovation project of school facilities for the 2021 Fiscal Year in Kupang City and Regency.

Roni is alleged to have committed unlawful acts from the planning stage to the disbursement of the project budget carried out by PT Jasa Mandiri Nusantara.

Prosecutors state that in 2020, the defendant made an agreement with Pethrus Riwu Rendok to appoint him as the Attorney Director of PT Jasa Mandiri Nusantara Kefamenanu Branch. The appointment was done by arranging official documents before a notary so that the company could participate in the tender for the school rehabilitation project in the Kupang area.

“After the appointment, the defendant directed the witness to participate in the tender, while also arranging for the company to be designated as the winner,” the prosecutor stated in the indictment.

Such actions are deemed to violate legal provisions, particularly regarding the prohibition of collusive practices in tenders as regulated in Law No. 5 of 1999 on the Prohibition of Monopolistic Practices and Unhealthy Business Competition, as well as Presidential Regulation No. 16 of 2018 on Government Procurement of Goods and Services, which has been amended by Perpres No. 12 of 2021.

After the work contract was signed on 26 February 2021, the defendant is also alleged to have diverted the work to other parties outside the company structure through a subcontracting mechanism that does not comply with regulations.

In practice, the contract value for each school is said to have been deducted by 10 percent tax and additional deductions up to 21 percent. Prosecutors assess that this contradicts the principles of efficiency, transparency, and accountability in government procurement of goods and services.

Furthermore, in the budget disbursement process, the defendant is alleged to have submitted a work performance payment request to PPK Hendro Ndolu by forging the signature of Pethrus TH Riwu Rendok as the Attorney Director.

“The signature forgery was done without the knowledge of the person concerned,” the prosecutor emphasised.

The payment request was then processed and approved by the PPK. The project funds were subsequently transferred to the BRI giro account of PT Jasa Mandiri Nusantara.

For the series of actions, the defendant is charged with violating various provisions in government procurement of goods and services as well as principles of healthy business competition.
