A total of 38 people have fallen victim to a hacker who stole their ATM information and withdrew Bt500,000 (S$19,400) cash from their accounts.
Pol Lt Khomsan Tutiyanon of Bangkok's Prachacheun Police Station said police had received complaints about ATM hacking since last Friday.
Police initially found that most victims had Siam Commercial Bank accounts and had at some point withdrawn money from an automated teller machine on Tesaban Songkhro Road in Lat Yao sub-district of Chatuchak district.
Most victims' money was withdrawn via an ATM at Songkhla's Hat Yai district, he said.
SCB has frozen the ATM cards of the 38 victims and will be responsible for the stolen money, he added.
