DSI chief Tarit Pengdith said investigation showed that Thewasit Phikhanet, Srisopa Marketing and Jumbo Supply and Service had signed 18 contracts with several cooperatives to provide them with lottery tickets at a cheaper price. However, in reality, these firms did not have contracts with the Government Lottery Office as claimed and failed to deliver any lotteries to the cooperatives.
The DSI initially wanted to sue 87 suspects, but it remained unclear if the coop executives had any hand in the corruption and several also suffered losses themselves. Hence, DSI agreed to use them as witnesses and decided to indict Srisuk and 13 others.
