Inside the sprawling Dhaveevatthana Palace in Bangkok is a prison built to lock up those betraying the trust of the new Thai king, Vajiralongkorn. On March 27, 2012, during the Yingluck Shinawatra administration, the Ministry of Justice issued an order regarding the construction of a prison within Dhaveevatthana Palace on a 60-sq.-meter plot of land. Named Buddha Monthon Temporary Prison, it is under the authority of the Klong Prem Central Prison.

The Dhaveevatthana prison has been officially legalized, therefore permitting King Vajiralongkorn to imprison anyone under its roof legally. Some of his close confidants have been imprisoned there, from Suriyan Sucharitpolwong (better known as Moh Yong) to police Maj. Prakrom Warunprapha and Maj. Gen. Phisitsak Seniwongse na Ayutthaya. They were behind Vajiralongkorn's "Bike for Mom" campaign in 2015, but were later found guilty of embezzling the project's funds. All died in the Dhaveevatthana prison under mysterious circumstances.

The latest high-profile inmate was Police Gen. Jumpol Manmai, a former deputy national police chief. The palace branded him as an extremely evil official. Exactly how Jumpol managed to upset the king remains unknown.
