Two Nigerian men and a 32-year-old Thai woman, Kanyathanat Thotsatham have been reportedly arrested in the Thalang district of the resort island province over alleged involvement in a romance scam.
Bangkok Post reports that the arrest took place on Thursday night, during a raid on a house in the Phatcharee Thalang housing estate, where over 50 sachets of cocaine and a digital balance were seized.
Samut Prakan Provincial Court had issued an arrest warrant on Ms Kanyathanat for public fraud and inputting false information into a computer system.
The two Nigerians were found to have overstayed their visas for 1,401 days and 1,728 days respectively.
The arresting team discovered that some foreign nationals from South Africa were part of a romance scam gang that operated by creating fake Facebook accounts to dupe people in Thailand into transferring money, Pol Lt Col Pitthaya Thepmuang, inspector of the Tourist Police Sub-Division 3, said.
According to the report, Police then identified Kanyathanat as working for the gang. She was tasked with withdrawing and transferring money to the bank accounts of a Nigerian gang leader living abroad, according to Pol Lt Col Pitthaya.
The Nigerian men were said to have confessed during questioning, to having been involved in a romance scam gang, and admitted to selling cocaine to foreign tourists in Phuket to earn extra income.
Meanwhile, all suspects were handed over to police at Thalang station for legal action.
