Meanwhile, Warinda Wonghakan, 25, was arrested in Khon Kaen province on Wednesday.
All three were charged with fraud, providing false information online and laundering money.
Warinda and other members of the gang allegedly sold 10,000 face masks and 1,000 face shields via Facebook for a total of US$12,9000 or about Bt421,000. However, customers were not sent the goods they reportedly bought.
