Pol General Somyot Pumpanmuang, national police chief, said Tuesday that police were looking for four other suspects and probably more, mostly foreigners.
The gang was believed to have operated since 2012 promising women jobs in China, Malaysia and Singapore.
The five were Sunatta Oopkaew, 32, who was nabbed in Samut Sakhon; Inthu-on Polpanchu, 25, and Pradit Thadee, 25, both caught in Bangkok; Srilakhon Thongkhao, 39, in Samut Prakan; and Jittanan Sithichai, 31, in Phuket.
Police spokesman Prawut Thawornsiri said this was one of the 34 human-trafficking gangs that Thailand presented in its update to the United States’ “Trafficking in Persons” report.
