[3][4][5] The DSI was formed on October 3, 2002 pursuant to the Ministries, Bureaus, and Departments Restructuring Act of 2002, in order to deal with rapid changes in global climates, political and societal changes, changes in violent crimes, technological development and exploitation of loopholes in the law.

DSI gave conflicting reports about how Tawatchai was found, with one official stating he likely committed suicide by hanging himself with his shirt.

[20] A post-mortem examination revealed that Tawatchai had died of a ruptured liver, suggesting blunt trauma, as well as suffocation.

[22] 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.

[24][25] 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.
