The arrest came shortly after Thanawat Khamhaengpol, better known as Pete, admitted that the whole story was a lie.
Thanawat, who sells lottery tickets at a petrol station in Samut Sakhon, was taken to Khok Kham Police Station for further questioning, according to Thai media reports.
The vendor won praise for his honesty after he claimed that he had safely kept and delivered the tickets, which won B90mn, to a customer who had placed an order via a mobile chat application.
The story quickly went viral.
He also posted a photo of the winning tickets, and later claimed the winning customer gave him a gift or B100,000 as a thank-you gesture. People turned up at the petrol station wanting to buy lottery tickets from him. Business boomed.
But the man went from hero to zero after sceptics decided to investigate and found out that the winning tickets were fabricated. Police came under pressure to take legal action against him.
According to media reports, he faces charges of fabricating lottery tickets and deceiving the public for personal gain. The Government Lottery Office is expected to file a formal complaint in connection with forgery of the tickets.
Currently he is charged with violating the computer crime law for posting false information online.
