Leadership Change at Thailand's DSI Amid Senate Election Probe

On September 23, 2026, the Thai Cabinet approved the appointment of Police Captain Piya Raksakul, currently the Director-General of the Department of Probation, as the new head of the Department of Special Investigation (DSI). This move involves the transfer of the incumbent, Police Major Yutthana Praedam, to a special expert position at the Office of the Prime Minister.

This leadership transition occurs at a critical juncture for the DSI, as it is currently investigating allegations of collusion in the recent Senate elections. Under Major Yutthana’s tenure, a joint committee between the Election Commission (EC) and the DSI had moved to prosecute 229 individuals linked to the case. Major Yutthana had previously faced scrutiny from the current government, partly due to his professional history and his role in leading investigations into money laundering and criminal association related to the election process.

For residents and observers, this change in leadership raises questions regarding the continuity and direction of the ongoing Senate election investigation. While political observers have previously speculated about potential leaks of case files to opposition groups and civil society organizations like iLaw, no evidence has confirmed the source of such information. It remains to be confirmed how this administrative reshuffle will impact the progress of the 229 pending cases and whether the investigation will maintain its current trajectory under new leadership.
