Bangkok police have arrested a couple for selling allegedly impure gold amulets, on suspicion of public fraud, computer crime and false advertising.

The arrest happened at the couple's house on Ram Intra 65 Road in Bang Khen district, Bangkok, on Monday.

The suspects are Kornkanok Suwannabut, 37, aka Mae Tuck and her husband Kanpon Rueang-aram, 35, aka Pa Bia. 

Police also searched their K2N gold shop on Hathairat Road in Khlong Sam Wa district, Bangkok.

Ms Kornkanok and her husband were accused of selling jewellery with less gold content than advertised during livestreaming sessions on social media.

Their business made headlines as many buyers said they could not sell the products at other gold shops because other gold traders doubted the real gold content in the products.

Police said that the couple denied all charges and refused to answer questions. Police rejected their bail request and would seek a court order to extend their detention on Tuesday. Police also seized gold, safes and four registered guns from the couple’s house for further examination.

Officers said that the couple owned luxury cars and investigators were following the money trails of the cars, other assets and cash belonging to the couple.
