# Thailand Senate election fraud investigation leak > Live situation record from CLSTR: https://clstr.news/situations/thailand-senate-election-fraud-investigation-leak > Updated: 2026-09-03T03:44:52.000Z. Sources: 4. Developments: 3. The Department of Special Investigation (DSI) in Thailand has launched an investigation into the unauthorized leak of confidential files concerning alleged Senate election fraud and money laundering. DSI Director-General Yuthana Praedam established a fact-finding committee to determine if internal officials facilitated the disclosure, which followed the public release of information by the organization iLaw. The DSI is pursuing legal action under the Criminal Code for the disclosure of official secrets, maintaining that the leak could damage ongoing legal proceedings. In response to the disclosure, Senator Pisit Apiwattana-pong criticized the release of the investigation reports by Parit Wacharasindhu of the People's Party and Yingcheep Atchanont of iLaw. The Senator questioned the accuracy of the leaked data and suggested the move was politically motivated to influence public opinion. He further raised concerns that the publication of personal information within the files might violate the Personal Data Protection Act (PDPA) and the Computer Crimes Act, describing the use of online media to present the data as a form of “vigilante justice” or “witch hunting.” Following the DSI’s complaint to the Crime Suppression Division, the Thai House of Representatives Police Committee has summoned People's Party MP Parit Wacharasindhu and iLaw Director Yingcheep Atchanon to clarify the disclosure of documents related to Special Case 24/2568. Wacharapong Kuwichitsuwann, Chairman of the Police Committee, denied that the summons is a political tactic to suppress information, stating the objective is to investigate how the leak occurred to maintain DSI credibility and ensure the integrity of the investigation. ## Claims - The Police Committee is investigating the leak of Department of Special Investigation (DSI) documents to find the facts.
