Police Colonel Krissana Pattanacharoen, deputy spokesman for the police force, said that the three suspects, all of them men, had been charged with taking part in a criminal syndicate, in addition to violations against the Computer Crime Act.
The three suspects were identified as Udon Thani resident Danai Pairoh, Chon Buri resident Jatuporn Wattanaponlasak, and Nakhon Pathom resident Chaowalit Chomphai.
The military handed over a 19-year-old suspect to police on Monday for his alleged involvement in the seemingly concerted hacking attacks. He was charged with the same offences as the other men.
