History
A Special Branch Bureau division exists in the Royal Thai Police, part of its Crime Prevention and Suppression Support Group. Aside from intelligence gathering, they provide protection to VIPs alongside the Bangkok Metropolitan Police Bureau and Armed Forces Security Centre. They handle matters that have to do with citizenship, such as the renunciation of Thai nationality. Foreign nationals living in Thailand go to the Special Branch office to secure a Thai police clearance certificate. Other cases such as lèse majesté, terrorism, and anything that endangers Thai national security are also handled by the Thai SBB. The SBB worked with the Malaysian Special Branch during the Cold War. During that time, SBB officers were involved in the Red Drum killings, in which 3,008 accused of being pro-communist were burned to death from red drums alive or semi-conscious and incinerated during the administration of Prime MinisterThanom Kittikachorn. The SBB was accused of human rights violations toward Falun Gong practitioners. They have been promoted as a means of routing political opposition to the government. The division stirred controversy in the run-up to the 2007 general election when media revealed that the SBB had conducted its own opinion poll to assess the probable electoral outcome. In response to similar stories before the 2011 general election, the SB characterised its gathering of data as a study rather than a poll. A special police unit called the "Black Tiger" is under the control of the Special Branch. It handles VIP protection operations.
