Every year on October 5, employees of the criminal investigation department of Russia celebrate their professional holiday.
The Russian detective even in Tsarist Russia showed its significance and strength. On October 5, 1918, the People's Commissariat of Internal Affairs of the RSFSR approved the Regulations on the organization of criminal investigation departments.
The Central Department of Criminal Investigation - Tsentrorozysk - was organized in October 1918. Since then, special subdivisions began to operate under the local militia "to maintain order by secretly investigating crimes of a criminal nature and combating banditry." Over the years, this service has been developed and improved.
