Jakarta. Indonesian police have enlisted assistance from the US Federal Bureau of Investigation (FBI) and the US Secret Service to help verify evidence seized in a sweeping corruption investigation involving former Deputy Attorney General for Special Crimes Febrie Adriansyah, who has been named a suspect.

Officials from both US agencies visited the Jakarta Metropolitan Police's Special Crimes Directorate on Tuesday to examine large amounts of US dollar cash confiscated during a series of raids linked to three corruption cases involving Febrie.

The representatives left police headquarters shortly before 1 p.m. local time after conducting the examination.

Jakarta Police spokesman Budi Hermanto previously said investigators were working with the US Embassy, the Singapore Embassy, the FBI, the US Secret Service, and Bank Indonesia to authenticate foreign currency seized during the investigation.

Separately, a joint team of investigators from the National Police, the Attorney General's Office (AGO), and state-owned pawnshop Pegadaian has begun verifying 74 kilograms of gold bars recovered during the operation.

According to police, the seized cash and gold are suspected proceeds of bribery linked to investigations into coal supplies for state-owned power plants, corruption cases involving state insurers Asabri and Jiwasraya, and debt restructuring at a subsidiary of Krakatau Steel.

Budi said the verification process forms part of preparations before the case file and evidence are formally transferred to the Attorney General's Office for prosecution.

The investigation has involved coordinated searches at 13 locations believed to be connected to the alleged corruption scheme.

At a residence in the Parahyangan Golf residential complex in Bogor, investigators seized 74 kilograms of gold bars, $4.77 million in cash, S$14.08 million, Rp 100 million ($5,900), and other evidence.

Police also searched a foreign exchange business, where they confiscated around Rp 4.46 billion in cash along with multiple foreign currencies, including US dollars, Singapore dollars, Saudi riyals, Thai baht, Turkish lira, Chinese yuan, Japanese yen, Malaysian ringgit, Indian rupees, Australian dollars, South Korean won, Brunei dollars, Vietnamese dong, and New Zealand dollars.

Another raid at De'Clan Cafe in South Jakarta uncovered S$3.13 million, $889,965, and Rp 259.15 million in cash, while a separate search at a house in Cilandak yielded Rp 520 million and $133,000.

Authorities said all seized assets are undergoing verification as part of the ongoing investigation before the case is handed over to prosecutors.

Later on Tuesday, a convoy of National Police investigators arrived at the Attorney General's Office headquarters in Jakarta to continue transferring investigative documents related to the case.

The officers were seen carrying a suitcase labeled with investigation files into the AGO's main building but declined to comment to reporters.

Attorney General's Office spokesman Anang Supriatna confirmed the visit was part of the administrative handover of the investigation.

The AGO has previously said it will establish a special prosecutorial team to review the case after receiving the files from police. The team will examine witness statements, evidence, and the legal construction of the case before deciding on the next steps.

Anang said prosecutors would continue coordinating with National Police investigators as well as the Corruption Eradication Commission (KPK) in its supervisory capacity.

He said the case would be handled professionally while upholding due process and the presumption of innocence.

Before becoming a suspect, Febrie oversaw many of Indonesia's largest corruption investigations, including illegal mining, the corruption case involving former communications minister Johnny G. Plate, cases involving state insurers, and the laptop procurement case involving former education minister Nadiem Makarim.

A day before resigning, Febrie defended his record in fighting corruption but declined to answer questions about the cash and gold seized during the investigation or whether he intended to step down. Instead, he urged the media not to speculate about the evidence collected by police.
