TULUNGAGUNG – The KPK investigation Tulungagung is intensifying, with 20 local government officials scheduled for questioning over a corruption case linked to the recent arrest of the region’s former regent.

Indonesia’s Corruption Eradication Commission (KPK) has summoned the officials for examination over three days, from April 22 to April 24. During this period, investigators are conducting the sessions at the East Java office of the Financial and Development Supervisory Agency (BPKP) in Surabaya.

Authorities are questioning the officials in stages as part of an ongoing probe into the arrest of former Tulungagung Regent Gatut Sunu Wibowo. Previously, the case emerged from a sting operation that led to his detention.

Acting Regent Ahmad Baharudin confirmed that several officials from the Tulungagung administration have received summonses. He added that the KPK arranged the questioning schedule across three consecutive days.

“Yes, the KPK has summoned several officials. The questioning runs from Wednesday until Friday,” he said.

Baharudin said he does not have detailed information about the scope of the investigation. He also declined to name the officials involved, noting that the matter falls entirely under KPK authority.

Head of the Legal Division at the Tulungagung Regional Secretariat, Candragupta Maurya, confirmed that 20 officials are taking part in the process. In addition, he said authorities divided the schedule across three days to manage the number of witnesses.

“A total of 20 officials have been called. The examinations take place over three days,” he said.

Candragupta added that his office handled the delivery of official summons letters. Even so, he declined to disclose the identities of those involved in the investigation.

Meanwhile, the KPK continues to deepen its probe following the earlier sting operation. Authorities have named two suspects in the case: Gatut Sunu Wibowo and his aide, Dwi Yoga Ambal.

Investigators have also conducted several searches at the regent’s official residence and government offices. Through these efforts, the KPK aims to trace the flow of funds and identify all parties involved.

The latest round of questioning shows that the investigation remains active. Authorities continue to gather testimonies as they work to build a clearer picture of the case.
