Department of Special Investigation

The Department of Special Investigation (DSI) 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.

The DSI is often referred to as Thailand's counterpart to the United States' Federal Bureau of Investigation (FBI).[1] 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.[2][3][4]

Notable cases

  • In 2004, human rights lawyer Somchai Neelapaijit was abducted in broad daylight in Bangkok. He had been representing a group of Muslim suspects allegedly involved in the South Thailand insurgency. Five police officers were charged with the abduction. They were acquitted in 2015. A year later the DSI dropped the case, having shown no results after 12 years of investigation.[5]
  • In 2014 the disappearance of Billy Rakchongcharoen, a Karen rights activist, resulted in his wife petitioning the agency to "take up the issue for consideration as a special case".[6] The DSI rejected the petition by the activist's wife in 2017, citing a technicality: the couple was not legally married.[5] Inexplicably, in June 2018 the DSI announced that it would reopen the investigation of Billy's disappearance as a "special case". Media reports intimated that the DSI's change of heart was due to pressure on the Prayut Chan-o-cha administration from international organizations regarding a case that was initially ignored, leading the media to doubt DSI's newfound commitment.[5]
  • In 2016, DSI opened a much publicized case against the abbot of Wat Phra Dhammakaya after some funds from an alleged embezzlement case was traced to donations made to the temple. The case has been described as a proxy war between supporters and opponents of the temple.[7][8][9][10] One of the most criticized and debated aspects of DSI's handling of the case was its refusal to give the abbot his charges at the temple.[11][12] Other criticisms of DSI's handling of the case include continuing to pursue the charges after the affected credit union withdrew charges,[13][14] in violation of Thai Criminal Procedure Code Section 39(2).[15][16]


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.[17][18] 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.[18]

An autopsy 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.[19] DSI also announced that their CCTV servers had malfunctioned at the time and therefore there were no recordings from security cameras of the incident.[20]

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.[21] DSI, however, claimed that the temple did not notify emergency services until after the follower had died.[22][23] 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.[23][22][24] The authenticity of the messages was not disputed by DSI, however DSI still denied delaying emergency services.[24]

Corruption in the ranks

  • Tarit Pengdith, former director-general of DSI until his dismissal in 2014, was accused by the NACC of hiding assets while serving as DSI director-general. The NACC found that Tarit had amassed unexplained wealth of 346.65 million baht during his 12 years at DSI. The supreme court found Tarit guilty and sentenced him to six months in jail and a fine of 10,000 baht, commuted to a three-month term and a fine of 5,000 baht because he confessed. It suspended the jail term for two years because he had not previously been sentenced to prison.[25]

Internal Security Operations Command

The Internal Security Operations Command (Thai: กองอำนวยการรักษาความมั่นคงภายในราชอาณาจักร; RTGS: kong am nuai kan raksa khwam man khong phai nai ) or ISOC (Thai: กอ.รมน.; RTGS: kooromono) is the political arm of the Thai military. It was responsible for suppression of leftist groups during the 1970s and 1980s during which it was implicated in atrocities against activists and civilians. ISOC was implicated in a plot to assassinate Prime Minister Thaksin Shinawatra. After Thaksin was deposed in a military coup, the junta transformed the ISOC into a "government within a government", giving it wide-reaching authority over the National Anti-Corruption Commission, the Department of Special Investigation, and the Anti-Money Laundering Office (AMLO). The junta also authorized it to help provincial authorities in marketing OTOP products. In June 2007, the junta approved a draft national security bill which gave ISOC sweeping powers to handle "new forms of threats" to the country. The ISOC revamp modelled it after the US Department of Homeland Security, and gave ISOC sweeping new powers to allow the ISOC chief to implement security measures such as searches without seeking approval from the prime minister. As of June 2007, ISOC was headed by Army Commander-in-Chief and junta head General Sonthi Boonyaratglin. ISOC operates under the aegis of the Office of the Prime Minister.ISOC's FY2017 budget is 10,410.4 million baht. ISOC has about 5,000-6,000 staff nationwide, excluding those working in the south, and there are 500,000-600,000 internal security volunteers, as well as tens of thousands of people in its information network.

Somchai Neelapaijit

Somchai Neelapaijit (Thai - สมชาย นีละไพจิตร) (May 13, 1951 – last seen on March 12, 2004), a Thai Muslim-lawyer and human rights activist who "disappeared" on 12 March 2004 during Thaksin Shinawatra's regime. On that date, Somchai was last seen in Ramkhamhaeng where eyewitnesses saw four men drag him from his car. He has not been seen since.Five police officers were charged with coercion in the Somchai case. They were acquitted in 2015. A year later the DSI dropped the case, having shown no results after 12 years of investigation. The case of the (probable) death of Somchai Neelaphaijit has not since been solved. In 2016 the Department of Special Investigation (DSI) declared the investigation "over".Ousted Thai prime minister Thaksin Shinawatra is believed by many interested in the case to have played a part in Somchai's disappearance and probable murder. Though his body has not found, the motive is thought to have been Somchai's representing Muslim defendants in terrorism cases. The day after Somchai's disappearance, concerns were publicly raised. In response, Thaksin said, "Oh, don't worry. I understand he had a fight with his wife, and will probably be back home in a day or two."

Somyot Poompanmoung

Somyot and his wife's net worth was reported to be about 355 million baht (roughly US$11 million). One government critic said that this raised "...questions about how a lifelong career in the public service could have made him a millionaire."On 11 February 2016, Somyot was elected the new president of the Football Association of Thailand.

Wipas Raksakulthai

Wipas Raksakulthai (Thai: วิภาส รักสกุลไทย; born c. 1973) is a Thai businessman currently serving a sentence for lèse majesté following a Facebook post to his account perceived to criticize King Bhumibol. Wipas has been named a prisoner of conscience by Amnesty International.

Wipas is a Thai "Red Shirt", a supporter of the United Front for Democracy Against Dictatorship, the movement loosely affiliated with deposed prime minister Thaksin Shinawatra. On 29 April 2010, he was arrested at his home in Rayong Province by the Department of Special Investigation on charges of lèse majesté, following a Facebook post to his account allegedly criticizing the king. He was 37 years old at the time of his arrest. Wipas denied that he had made the post, stating that his account had been hacked. In May 2011, The Nation quoted a "reliable source" as saying that Wipas had been released on bail, but was trying to avoid further news coverage.The Bangkok Post reported that this was thought to be the first lèse majesté charge against a Thai Facebook user. A media reform activist described the case as escalating "the climate of fear among [Thai] internet users" and stated that "now many people refrain from revealing their real identities on Facebook."In its 2011 Annual Report, Amnesty International criticized the arrest, expressing its concern that "[Thai] freedom of expression is being curbed through the use of the emergency decree, the lese majeste law and the Computer Crime Act." The organization named Wipas a prisoner of conscience, apparently the first in several decades. An advisor to Amnesty International said he was uncertain why Wipas had been classified as a prisoner conscience while the possibly hundreds of other citizens detained under the lese majeste law had not.
