BANGKOK – Cyber police have arrested the secretary to the Samut Prakan Provincial Administrative Organization (PAO) chief after investigators tied him to an alleged online investment fraud network.

On Tuesday, Pol. Lt. Gen. Surapol Prembutr, head of the Cyber Crime Investigation Bureau, led a joint operation with senior officers and more than 40 Anti-Money Laundering Office (AMLO) officials. The team used warrants from the Samut Prakan Provincial Court to raid five locations across Samut Prakan Province.

One key target was a luxury condominium unit near Bangna-Trat Road in Bang Phli District. There, officers arrested Sitthichai Chueathai, 35, who held the role of secretary to the Samut Prakan PAO chief. Police said he was wanted under arrest warrants issued by the Samut Prakan Provincial Court (No. J.209/2569, dated March 2, 2026) and the Rayong Provincial Court (No. J.137/2569, dated March 2, 2026).

Authorities listed the alleged offenses as supporting public fraud committed by impersonation, and supporting the act of dishonestly or deceptively uploading false or distorted computer data into a computer system.

Cyber Police Seize Evidence

Cyber Police also seized items they believe may relate to the case, including one laptop, five mobile phones, one portable hard drive, two cars, one company stamp for BB Venture Co., Ltd., and 41 bank passbooks.

In addition to the condo search, officers inspected two company locations in Samut Prakan. The first was BB Trading and Procurement Co., Ltd., a construction contracting business registered on December 9, 2014, located in Tai Ban Mai Subdistrict, Mueang Samut Prakan District.

The second was BB Investing Co., Ltd., registered on March 23, 2023, described as operating a foreign currency exchange-related business, also located in Tai Ban Mai. Police said Sitthichai served as a director and shareholder in these companies. Investigators collected documents and other evidence for further review.

According to Pol. Maj. Gen. Thinakorn Rangmat’s questioning of the suspect showed that he claimed to work in digital coin trading. He denied involvement with scammer groups or call center gangs. He also said he didn’t know the identity of people transferring money to buy or sell digital assets, describing it as normal buy-and-sell trading.

However, investigators said they remain unconvinced. Their inquiry reportedly found multiple complaints in the online police reporting system, many linked to investment fraud and stock trading scams, that connected to accounts tied to the suspect, both personal and corporate.

Cyber Police said they will allow the suspect to provide evidence to explain the transactions, and they plan to coordinate with his agency to follow the next steps.
