Department of Special Investigation


The Department of Special Investigation is a department of the Ministry of Justice of Thailand. It operates independently of the Royal Thai Police and is tasked with the investigation of certain "special cases". These include complex criminal cases, those affecting national security, those involving organised criminal organisations and those potentially implicating high-ranking government officials or police officers. As of June 24, 2020 the DSI is tasked to investigate and follow up on cases under the Prevention and Suppression of Torture and Enforced Disappearances if and when it becomes law on cases involving torture or forced disappearances.
The DSI is often referred to as Thailand's counterpart to the United States' Federal Bureau of Investigation. Since its inception, the DSI has seen conflicts with the police over jurisdiction and authority over cases, and department officials have publicly expressed concern that the department's work has been consistently subject to political interference.
Police Lieutenant Colonel Korawat Panprapakorn was named DSI Director-General in April 2020. The position had been vacant since Police Colonel Paisit Wongmuang's resignation in February for health reasons.

Budget

The DSI's budget for fiscal year 2019 was 1,190 million baht, up from 1,102 million baht in FY2018.

Tawatchai Incident

On 30 August 2016 it was reported by DSI that one of the suspects it had detained was allegedly found unconscious and hanging in his cell. The suspect, Tawatchai Anukul, who was a suspect in a case of land deed fraud, was then rushed to Mongkutwattana Hospital where he was pronounced dead after several attempts at revival. DSI gave conflicting reports about how Tawatchai was found, with one official stating he likely committed suicide by hanging himself with his shirt. Another official gave a report stating he was found hanging by his socks. Tawatchai's family reported that DSI gave them contradictory information regarding his death. For instance, family members pointed out that the wound on Tawatchai's neck looked like it came from a wire rather than clothing.
A post-mortem examination revealed that Tawatchai had died of a ruptured liver, suggesting blunt trauma, as well as suffocation. DSI stated that the liver rupture was due to the hospital team performing CPR on Tawatchai in an attempt to revive him, which the hospital dismissed as impossible. DSI also announced that their CCTV servers had malfunctioned at the time and therefore there were no recordings from security cameras of the incident.

Article 44 death

During the 23 day lock down of Wat Phra Dhammakaya in 2017 that junta leader Prayut Chan-o-cha ordered using article 44 of the interim constitution, one follower in the temple died of an asthma attack during the operation. According to temple spokespeople, the death was caused by the halting of an ambulance at the junta's blockade that delayed emergency response. DSI, however, claimed that the temple did not notify emergency services until after the follower had died. DSI stepped back from this statement later, when the temple revealed time stamped LINE messages asking for emergency services that supported Wat Phra Dhammakaya's account of the timeline. The authenticity of the messages was not disputed by DSI, however DSI still denied delaying emergency services.
