Lured by high returns, 25 victims lost millions to a Ponzi-style online savings scheme
What began as a friendly online savings group turned into a nightmare for 25 Indonesians, after a young housewife allegedly swindled them out of IDR 356 million. Her lavish spending finally led authorities to track her down in Batam.
From Arisan (Social Gathering) to Arrest
A 23-year-old woman identified as Octa Cahyu Pradini was arrested in Batam for defrauding 25 people through an online social gathering (community savings) scheme. The Muara Enim, South Sumatra resident collected IDR 356 million (approx. SGD 28,500) by promising high returns. Her arrest followed a detailed investigation by the Lawang Kidul police, triggered by a victim’s report.
Arisan is a rotating credit society where people pool money and then take turns receiving it
The fraudulent scheme, which began in November 2024, lured participants with initial payouts to gain their trust. Victims, many of whom transferred IDR 15 million each, were promised more if they reinvested. When payouts stopped, suspicions grew.
Ponzi Scheme In Disguise
According to Iptu Andaru Galuh Indratno, the case fits the classic Ponzi structure. Initial returns were paid using funds from new participants. Octa used part of the money to purchase a house, a car, and to pay off previous debts in a “rob Peter to pay Paul” cycle.
“Everything seemed legit at first. But by April 2025, payments began to be delay. That’s when complaints surged,” Andaru explained during a press conference on June 3, 2025.
Escape Attempt Foiled
As pressure mounted, Octa attempted to flee to Batam. A coordinated effort between Lawang Kidul police, Bandara Batam security, and Polres Balerang led to her capture at Batam Airport on May 24, 2025, at 8:00 PM.
Officers seized a pink iPhone 15 Pro and a transaction statement linked to her personal account. She now faces charges under Articles 378 and/or 372 of the Indonesian Criminal Code, carrying a maximum prison sentence of four years.
Another Case Emerges in East Java
Coincidentally, another case surfaced involving Ernawati (30), a woman from Mojokerto accused of defrauding six victims of IDR 653 million through a similar auction-style savings scam. Arrested while hiding in Pasuruan, she now awaits legal proceedings while six months pregnant.
Police confirmed her arrest and encouraged victims to come forward. One victim, TT (34), expressed hope that her money—around IDR 32 million—would be recovered.
Caution for the Community
Both cases highlight a rising trend in online financial scams disguised as social gathering groups. The police urge the public to verify legal standing before participating in online investment offers, particularly those that promise unusually high returns.
Muara Enim Police continue to investigate potential additional victims beyond the 25 identified so far, as the scam was operated via online platforms.
The social gathering fraud cases underscore the vulnerability of online trust-based financial networks in Indonesia. As digital schemes grow in popularity, both Indonesians and Singaporeans with cross-border connections must remain vigilant. These incidents are stark reminders of the need for financial literacy and caution in the face of too-good-to-be-true offers.
