BANGKOK, Thailand – Police have arrested former bank employee Sasipim, 40, and three alleged accomplices accused of deceiving five VIP banking customers into investing in a fake “special debenture” scheme, causing reported losses of more than 78 million baht. The Economic Crime Suppression Division (ECD) carried out arrests in Bangkok, Nakhon Sawan, Nonthaburi and Pathum Thani following arrest warrants issued by the Criminal Court. The suspects face charges of jointly committing fraud and a financial institution employee unlawfully seeking benefits for themselves or others, causing damage to the financial institution.
Police identified the suspects as Sasipim, 40; Saengchan, 37; Pornchai, 57; and Thatasit, 45. Investigators also seized documents and financial evidence, including eight sets of company documents, four sets of case-related documents, five bank cheque books, 32 cash cheques, two cash cards, 11 bank account books and three mobile phones. The investigation began after a commercial bank reported the case to police after five of its high-value customers, each with assets exceeding 10 million baht, allegedly fell victim to the scheme. Police said Sasipim, who previously worked as an assistant district manager and relationship manager (RM), allegedly approached the customers and encouraged them to invest in a product described as a “special debenture”. She allegedly promised returns of 2% every three months, or around 6–7% within a three- to six-month period.
Investigators said the scheme initially appeared legitimate because investors received returns as promised during the early stages. This allegedly encouraged them to invest larger amounts before payments later stopped. The bank later conducted an internal investigation and provided compensation to the affected customers before filing a criminal complaint against those allegedly involved. Police allege that Sasipim worked with three other suspects, including Pornchai, who allegedly acted as an investment adviser; Thatasit, who allegedly received transferred funds from investors; and Saengchan, a company director whose business was allegedly used as a nominee entity to receive investment money.
According to investigators, the company involved was registered as a waste management and disposal business and had no connection with the bank. Police allege it was used as a channel to receive investment funds. Financial investigations found money flows linked to the group between 2020 and 2025, with total transactions estimated at around 350 million baht. After collecting evidence, police obtained arrest warrants and detained all four suspects. During questioning, all suspects denied the allegations. They were handed over to investigators from the Economic Crime Suppression Division for further legal proceedings.
