Former Bank Branch Manager Convicted of IDR 5 Billion Investment Fraud Scheme in Surabaya Court

An Indonesian court has convicted two individuals of a 5 billion rupiah investment fraud scheme. The former bank branch manager received a 2.5-year sentence while his accomplice received 1.5 years. Victims were lured with promises of 13% annual returns on non-bank deposits, but their funds were secretly diverted to stock trading without consent.

Case Overview

On September 21, 2026, the Surabaya District Court (PN Surabaya) convicted two individuals in a major investment fraud case. Ranto Hensa Berlin Sidauruk received a 2.5-year prison sentence, while Agustin Widyawati received 1.5 years.

How the Fraud Worked

The scheme began in January 2019. Ranto, a former bank branch manager and college friend of the victim, offered investment in non-bank deposits with promised annual returns of 13%. The victim, Salim Himawan Saputra, gradually invested until reaching 5 billion rupiah (approximately USD 315,000). Ranto claimed these funds would be guaranteed by stocks worth double the investment amount.

Agustin played a supporting role, meeting the victim at a shopping mall to convince him of the investment's safety.

Misuse of Funds

Instead of the described investment, the 5 billion rupiah was channeled through a corporate bank account into stock purchases (codes IKAI and TOPS) under a repurchase agreement (REPO) scheme—a complex financial transaction never disclosed to the victim. When the investment matured, the victim received only interest payments; the principal amount was never returned.

Trial and Verdict

The defendants denied fraud charges, claiming corporate default rather than intentional deception. Ranto argued he never directly controlled the funds since they went into a corporate account. The court disagreed, finding both guilty as charged. The sentences were lighter than the prosecutor's demands of 3 years 3 months for Ranto and 2 years for Agustin.

Warning Signs and Prevention

Red flags in this scheme:

Unusually high returns: Interest rates significantly above market average (13% in this case) are a major warning sign
Non-bank financial products: Even when presented by banking professionals, unregistered investment products are high-risk
Vague fund usage: Demands for detailed, written explanations of how your money will be invested. Opacity indicates danger
Personal relationships: Trust in the person offering is not a substitute for proper due diligence
Regulatory verification: Always verify that investment sellers are registered with financial authorities before investing

Where to Report

If you encounter suspicious investment solicitations or suspect fraud, contact local law enforcement or financial regulatory authorities immediately.
