Thailand-Central Investigation Bureau

Having jurisdiction over the entire country, the Central Investigation Bureau was organized to assist both provincial and metropolitan components of the TNPD in preventing and suppressing criminal activity and in minimizing threats to national security. The specialized units of the bureau, including the railroad, marine, highway, and forestry police, employed up-to-date technical equipment, law enforcement techniques, and training.

In addition to the specialized units, five other divisions and offices employed modern procedures to assist in investigating and preventing crime. The Crime Suppression Division--one of the bureau's largest components--was responsible for conducting most of the technical investigations of criminal offenses throughout the kingdom. Its emergency unit coped with riots and other public disorders, sabotage, counterfeiting, fraud, illegal gambling operations, narcotics trafficking, and the activities of secret societies and organized criminal associations. The Special Branch--sometimes referred to by critics as the "political police"--was responsible for controlling subversive activities and served as the TNPD's chief intelligence organization. The Criminal Records Office collected and maintained records required in the conduct of police work, including dossiers and fingerprints of known criminals and persons suspected of wrongdoing . At the well-equipped Scientific Crime Detection Laboratory, technicians performed the requisite chemical and physical analyses. The Licenses Division registered and licensed firearms, vehicles, gambling establishments, and various other items and enterprises as required by law.
