Thailand arrests crypto exchange suspect in 500m yuan laundering case

Thai immigration police have arrested a 37-year-old Chinese man accused of exchanging cryptocurrency and foreign currency for a laundering network linked to more than 500 million yuan in transactions.

The Nation reported on Oct. 17 that investigators detained the suspect, identified only as Wu, at a luxury housing estate in Bangkok’s Saphan Sung district a day earlier.

Investigators said Wu was wanted in China over offenses connected with a loan-sharking gang. In Thailand, officers charged him with overstaying his permission to remain in the country and transferred him for legal proceedings before arranging his return.

Police allege crypto exchange and bank-account recruitment

According to the police account carried by local outlets, Wu helped recruit people to open bank accounts, collected their bank cards and account details, and supplied them to money-laundering groups.

The alleged operation combined access to bank accounts with exchanges between digital currencies and foreign currencies. Investigators placed the network’s transaction volume above 500 million yuan, without describing the entire amount as cryptocurrency transfers.

Khaosod English’s Oct. 17 account said Wu arranged visas for people linked to transnational criminal networks involved in other suspected laundering cases. Police described his role as providing financial and logistical services to criminal groups.

Thai-language outlet Thaitabloid reported that investigators from Immigration Division 3 used information from international police channels to pursue the suspect. Officers eventually traced him to a property in the Ramkhamhaeng area of Saphan Sung.

During the search, investigators alleged that Wu had used forged documents to register his accommodation. They said he changed vehicle registration plates and covered his car with a different-colored wrap to make his movements harder to follow.

Thai overstay charge precedes planned return to China

Immigration checks found that Wu’s permission to stay had expired approximately three years and eight months earlier, according to local reports.

Officers charged him under Section 81 of Thailand’s Immigration Act 1979 with remaining in the country after his permission had expired. The reported Thai charge concerns his immigration status, while the outstanding Chinese warrant concerns the alleged criminal activity.

Authorities said they would begin deportation procedures and coordinate with Chinese officials over his return. The Nation reported that officers handed him to investigators for the Thai proceedings.

The Immigration Bureau said its units would continue screening foreign nationals and pursuing fugitives, including suspects connected with mule accounts and money laundering.

Thailand has pursued crypto-to-gold and cross-chain laundering cases

In August 2025, crypto.news previously reported that Thai police arrested a South Korean suspect in a separate crypto-to-gold laundering investigation involving more than $50 million.

Authorities alleged that wallets linked to the man, identified as Han, processed more than 47 million USDT between January and March 2024. Investigators said the funds bought gold through at least 30 transactions, each involving at least 10 kilograms.

Han was detained at Suvarnabhumi Airport on Aug. 23, 2025. Police had already made 10 arrests in that investigation, including five suspects accused of laundering money and others accused of operating mule bank accounts.

A separate international fraud crackdown announced in July 2026 resulted in 5,811 arrests across 97 countries and territories, according to INTERPOL. Operation First Light ran from Jan. 15 through April 30 and intercepted $293 million in illicit assets.

Within that operation, Thai authorities arrested two suspects accused of moving romance-scam proceeds through several cryptocurrencies and cross-chain token swaps. INTERPOL said a wallet associated with a 20-year-old suspect processed more than $122.5 million over 10 months.

Regulators have examined large stablecoin and cash transactions

In July, the Bank of Thailand and the Securities and Exchange Commission were examining high-value USDT transactions for possible concealed ownership and attempts to bypass domestic remittance channels, according to reporting on the authorities’ plans.

The central bank planned source-of-funds checks for cash deposits of at least 5 million baht, with implementation expected in the fourth quarter of 2026. Earlier withdrawal controls required customers to provide a verified business reason for taking out cash above that threshold.

Separately, Thailand’s Department of Special Investigation said in a June statement, updated in July, that a crypto-mining investigation had uncovered suspected laundering linked to cyberfraud and online gambling.

The agency said associated accounts and companies recorded more than 10 billion baht in annual transactions. It reported information from American authorities concerning a suspect identified in its English statement as Wang Yi Chen and said the US Secret Service had seized approximately $17.8 million in linked digital assets.

In a July 21 government statement, Thailand said Prime Minister Anutin Charnvirakul and FBI Director Kash Patel agreed to strengthen information sharing against transnational crime. The statement identified cooperation against scam networks as a focus of their meeting in Bangkok.

According to the government account, the FBI thanked Thailand for co-hosting a summit on scam centers on July 20–21. Both parties agreed to pursue cooperation against criminal networks alongside efforts to arrest individual offenders.
