Investigators from the Immigration Bureau arrested Iacob Corne, 39, of Romania, and Gim Teck We, 33, a Malaysian national, at a hotel in Hua Hin, the beach resort town in Prachuap Khiri Khan.
Seized from them were hundreds of fake electronic cards, six bank passbooks and mobile phones, report the Bangkok Post.
The arrests were made after police, working with Kasikornbank, found that money had been withdrawn from the accounts of many people, Pol Maj Gen Archayon Kraithong, deputy commissioner of the Immigration Bureau, said at a briefing on Friday (Oct 8).
Investigators discovered that skimming devices, which can capture data from cards inserted into an ATM, had been installed on bank machines at various locations in Bangkok and Hua Hin, he said.
During questioning, police said, the suspects confessed to having committed the thefts for over three months, mostly in tourist areas by installing skimmers on ATMs in the morning and withdrawing money at night.
The initial investigation found many victims lost several million baht to the duo, said Maj Gen Archayon.
