Sukanya Noiwong, 34, Prasong Chuasuk, and Suriya Amornpibulchai, 52, were arrested and 12 fake driving licences were found in an apartment in Nonthaburi's Muang district earlier this week, Sanit said.
He added that they would ask a customer to wire Bt3,000 per driving licence to a prepared bank account and they would send the fake document to the customer via post.
Sanit said Sukanya and her husband Prasong confessed to dealing with customers. Suriya had connections with another man nicknamed “Ek” who produced the forged documents.
The couple claimed they got Bt250 per document as they had to pay “Ek” Bt1,500 for each document and the rest went to Suriya.
The three suspects were initially charged with forgery.
The arrests followed an online investigation method by police that led to the arrest of four people for selling fake academic credentials via social media on April 9.
