Seven South Koreans were arrested when police raided a suspected telephone-fraud call centre operating inside a Sukhumvit area condominium Tuesday.
Crime Suppression Division and Khlong Tan police launched the operation on a tip that a group of Koreans had suspected of illegal activities since May 27.
Police found they frequently went in and out of the building moved to arrest the seven tenants at the condo block on Soi Sukhumvit 42.
The suspects were identified as Park Jihun, Kim Yun-do, Lee Kwang-sun, Seon Do-won, Noh Sang-mun, Jang Chang-yuk and Ha Heo-na.

Police seized eight notebook computers, seven phones, seven routers and bank books showing millions of South Korean won transactions.
Pol Lt Col Torsak Sukwimol, chief of the CSD's special operation unit, said the suspects used the room as their command centre to call scam victims in South Korea. They claimed to be bank officials asking bank customers to transfer the money to their accounts.
All were initially charged for illegally working in Thailand and could face additional charges of operating an illegal call centre after the damages are assessed, he added.
