– Royal Thai Immigration Division 5 detained Sun Hao, 40, a Chinese national, at a hotel in the Chang Khlan subdistrict in Mueang Chiang Mai, on the 9th of October after a tip about a suspicious guest.
– Chinese authorities want him on a fraud warrant. The alleged losses exceed 20 million yuan, or more than 100 million baht. Officers believe he fled to Chiang Mai to avoid the case.
– He entered Thailand on the 5th of April 2026 on a tourist visa valid until the 3rd of June, then held a student extension until the 7th of August. By the arrest he was more than 62 days overstayed.
– He was charged with remaining after his visa permission ended and sent to Mueang Chiang Mai Police Station. Any return to China is a separate process.
Chiang Mai Immigration officers arrested a 40-year-old Chinese man at a hotel in Chang Khlan on Friday, October 9th, after checks showed he had overstayed over two months and that Chinese authorities want him in a fraud case worth more than 100 million baht.
Pol. Maj. Wichai Kawichai, investigation inspector with Immigration Division 5, led the unit into the hotel room. Officers had received information about a Chinese guest whose behaviour was considered suspicious. Passport and biometrics records showed the man, identified as Sun Hao, entered Thailand on the 5th of April 2026 on a tourist visa that allowed him to stay until the 3rd of June. On the day of the arrest his visa permission had been expired for more than 62 days.
Further checks found a Chinese arrest warrant for fraud, with alleged losses of more than 20 million yuan, equivalent to more than 100 million baht. Immigration said he was believed to have come to Chiang Mai to evade prosecution in China. The fraud allegation has not been tested in a Thai court. It is the Chinese case file that Thai officers used to identify him.
He was charged as a foreigner who remained in the kingdom after his permission to stay had ended, and was handed to Mueang Chiang Mai Police Station. Authorities said they expect to start the process of returning him to China to face the warrant there. That step is separate from the Thai immigration charge and has not been completed.
The pattern is familiar this week. On the 7th of October, Royal Thai Immigration Bureau investigators arrested a 41-year-old Chinese former bank manager at a Pattaya condominium after a seven-year overstay and a Chinese embezzlement warrant.
Overstay is processed under the Immigration Act. In practice it can bring a daily fine, commonly cited at 500 baht a day and capped at 20,000 baht, plus detention and removal. Longer overstays feed into re-entry bans. None of that replaces, or decides, the Chinese fraud case.
