The National Police Agency has compiled a manual to help police nationwide cooperate on dealing with organized crimes committed by Japanese and foreign syndicates, agency officials said Monday.
After setting up a department in charge of organized crime in the Criminal Investigation Bureau in April, it scrapped manuals written separately by several departments and compiled the comprehensive version.
The manual is intended to deal with growing crimes such as drug and arms trafficking, the NPA said.
The manual encourages the use of wiretapping and controlled deliveries of packages known to contain contraband items to snare recipients.
NPA Commissioner General Iwao Uruma told a meeting of top prefectural police officers, "I would like you to continue efforts to restore safety and public faith in the police."
The agency aims to investigate the connections among Japanese organized crime groups and among international gangs. It added it will call for international cooperation to clamp down on drug trafficking.
