The arrest was executed by Thailand's Tech Crime Suppression Department (TCSD) on Saturday. Han, 33, is accused of fraud, computer crime, money laundering, and involvement in a criminal group. Investigators coordinated with immigration officials to apprehend him, and his mobile phone, containing multiple cryptocurrency accounts tied to a laundering network, was confiscated.
