Suwichan Saengkaeo, 25, an employee of the Ratchadaphisek-Lat Phrao branch, had earlier confessed to stealing amulets and other valuables worth a combined Bt25 million from the boxes, according to police.
The suspect yesterday gave police more information on where he had sold the items. Police took the case to the criminal court.
Police said Suwichan sold dozens of amulets at Pantip Plaza Ngamwongwan and sold gold ornaments in the Yaowarat area. They were able to retrieve some of the sold contraband, while other allegedly stolen objects were found in his condominium in the Lat Phrao area, they said.
They warned anyone who had purchased items from Suwichan to talk to police or face charges.
Police said the victims were bank employees who had deposited assets there for safekeeping. Suwichan reportedly confessed to using stolen keys to the boxes to steal their contents in May. He later sold them to pay his debts, they said.
