Ko Myo, a 42-year-old Myanmar national, was captured in a raid by police and justice officials on August 1 in Thailand's southern province of Surat Thani and faces human trafficking charges, said Police Maj Gen Chavalit Sawangpuech.
"This is a very significant case as Ko Myo is the leader of one of most notorious human trafficking rings in Thailand," Chavalit said. "He is an agent with a large client base, who has abused his own countrymen on Thai soil for 10 years".
Chavalit said police were also investigating his alleged involvement in the rape and killing of a Myanmar woman in March in Thailand's Trang province, on the Andaman coast.
Three of Ko Myo's close aides were arrested in separate raids. All three face human trafficking charges, while two were also charged with rape and murder of the same Myanmar woman.
Chavalit said Thai police would reach out to their counterparts in Myanmar to try to arrest more human trafficking suspects.
The London-based Environmental Justice Foundation said in a statement yesterday that it welcomed the capture of the suspects and called for parties "to work together to prevent human trafficking in Thai seafood production and bring an end to this devastating practice.
