Scammers posed as M1 and MAS officers in a complex fraud case that spanned eight days, exploiting fake QR codes and cryptocurrency transfers.

A Singapore man lost more than S$1.1 million (US$850,000) in just one week after falling victim to a sophisticated government official impersonation scam, where fraudsters posed as officers from the Monetary Authority of Singapore (MAS). The case has led to the arrest of 24 people aged between 15 and 34, with another nine under investigation, following an extensive police operation.

A Scam That Began With a Phone Call

The elaborate scam began on October 14, 2025, when the victim received an unsolicited call from someone pretending to be an M1 staff member. The caller falsely claimed there was an existing mobile plan under the victim’s name. After the victim denied it, the scammer said the matter would be escalated to MAS for investigation into an “information leak.”

Soon after, the victim received further calls from individuals posing as MAS officers, alleging that one of his bank accounts had been frozen due to suspicious activities. The scammers then convinced the victim to “safeguard” his money and assets by transferring them to various accounts for verification purposes.

Over S$1.1 Million Lost in a Week

Between October 14 and October 22, the victim followed the scammers’ instructions and transferred over S$1.1 million through multiple channels, including:

• S$350,000 in gold bars, handed to an unknown woman twice
• S$124,900 in cryptocurrency, transferred to wallet addresses controlled by scammers
• Over S$600,000 via more than 60 YouTrip QR code payments
• S$26,500 through PayNow to a local bank account

The scammers also instructed the victim to open a cryptocurrency trading account and make payments using YouTrip QR codes generated by them. Each transaction directed funds straight into scam-linked wallets.

Bank Alerts and Anti-Scam Intervention

On at least two occasions, the victim’s bank flagged suspicious transactions. However, coached by the scammers, the victim falsely claimed the transfers were for “investments” and “gifts.”

The deception was uncovered on October 22, when OCBC Bank detected repeated suspicious transfers and alerted the Anti-Scam Centre, which swiftly intervened and convinced the victim he had been scammed. Investigations revealed that most funds had already been withdrawn from overseas ATMs or transferred online within hours.

24 Arrested in Islandwide Operation

Following the report, the police launched an islandwide operation between October 23 and 24, resulting in 24 arrests and nine additional suspects under investigation.
Authorities found that several suspects had sold or rented their payment accounts to criminal syndicates, handing over their bank cards or login credentials. Two of the individuals were also discovered to be scam victims themselves, having opened YouTrip accounts under scammers’ instructions — losing S$1,600 and S$210,000, respectively.

Legal Action and Offences

The suspects are being investigated for offences including cheating, abetting unauthorised computer access, and money laundering.

• Cheating carries a jail term of up to three years, a fine, or both.
• Facilitating unauthorised access to computer systems can result in up to two years’ imprisonment or a fine.
• Assisting in money laundering can lead to three years’ imprisonment or a fine.

Police Advisory: Be Alert, Not a Victim

Authorities reiterated that Singapore government agencies, including MAS, will never:

• Ask for money transfers;
• Request banking log-in credentials;
• Ask to install mobile apps from unofficial stores; or
• Transfer calls to the police.

“Never allow others to use your bank accounts or mobile lines,” police warned. “You will be held accountable if they are linked to crimes.”

This latest case highlights the alarming sophistication of scam syndicates operating across digital and financial platforms. While authorities continue to strengthen anti-scam measures, public awareness remains the strongest line of defence. The swift action by OCBC and the Anti-Scam Centre prevented further loss — a reminder that vigilance and early detection can save lives and livelihoods in an era of increasingly complex financial fraud.
