Klaten Regent, Central Java BPN Chief and Private-Sector Figure Named as Suspects
JAKARTA — Indonesia’s Corruption Eradication Commission (KPK) has named three suspects following a sting operation into alleged corruption within the Klaten Regency Government during the 2025–2026 budget years. One of the suspects is Hamenang Wajar Ismoyo, Klaten Regent for the 2025–2030 term.
During the operation, KPK investigators detained 23 people on 15 October 2026 at three locations: Klaten, Surakarta and Jakarta. Ten of them were taken to the KPK’s Red-and-White Building for further questioning. The investigation eventually focused on three suspects.
“After finding indications of a criminal corruption offence, the KPK held a case review at leadership level and decided to move the matter to the investigation stage. Once sufficient evidence had been established during the investigation, the KPK named three people as suspects,” acting KPK Director of Investigations Achmad Taufik Husein said on Friday (16 October 2026).
The suspects are Hamenang Wajar Ismoyo; Ahmad Luthfi H. Rahmatullah, head of the Central Java BPK office; and Muhammad Amin Wahyu Utomo, a private-sector figure from PT Madani Winasis Creative (MWC). The KPK has detained all three for an initial 20 days, from 16 October to 4 November 2026.
“They are being held at the detention facility at the KPK’s Red-and-White Building,” Taufik said.
