About Us

Crime Wing

Comprises a Headquarters and a Support Group plus:

Commercial Crime Bureau

Investigates serious and complex commercial fraud; computer crime; and the counterfeiting or forgery of currency, coinage, credit cards, other commercial instruments and travel and identity documents.

Criminal Intelligence Bureau

Cultivates information in relation to criminal activities, societies, organised and serious crime. It conducts research on such activities and mounts intelligence-based operations against the syndicates involved, enabling strategic and tactical intelligence to be produced for enforcement action mainly by the OCTB and regional crime formations. The Bureau also has a dedicated role in kidnapping and terrorist incidents.

Criminal Records Bureau

Is the HKSAR's sole repository for all criminal records, maintaining a variety of indices of convicted criminals, wanted persons, suspected offenders, missing persons, stolen property, outstanding warrants and missing vehicles.

Cyber Security and Technology Crime Bureau

In order to effectively combat increasingly sophisticated technology crimes and maintain a safe cyberspace for Hong Kong, the Technology Crime Division of the Commercial Crime Bureau (TCD CCB) has been upgraded to a new Crime Wing Bureau known as the Cyber Security and Technology Crime Bureau (CSTCB) since 1 January 2015.

CSTCB is charged with the primary responsibilities of maintaining the cyber security of Hong Kong and preventing and detecting technology crimes. The establishment of CSTCB would further enhance the Force’s capability in combating technology crimes and handling cyber security incidents.

Financial Intelligence and Investigation Bureau

is established in June 2021 and responsible for money laundering and terrorist financing investigations, financial intelligence analysis, intelligence exchange with other local and foreign law enforcement agencies, as well as liaison with financial institutions and other stakeholders. It also looks after the anti-money laundering and counter terrorist financing policies and legislative matters in the Force and conducts ongoing territory-wide money laundering and terrorist financing risk assessment.

Forensic Firearms Examination Division

is the HKSAR's sole agency on the forensic examination of arms and ammunition. It also provides technical support for non-crime matters such as evaluating the performance of ammunition for the Force. As the sole repository for fired ammunition of undetected crime cases, this Division compares such fired ammunition against related exhibits recovered in fresh crime cases to identify any connections.

Identification Bureau

Is the authority on all matters relating to both fingerprints and photographs. It is responsible for the detection and identification of fingerprints from scenes of crime and giving expert evidence of identity in court.

Narcotics Bureau

Is responsible for collecting intelligence about the import, manufacture and distribution of dangerous drugs within the HKSAR and abroad. It takes direct enforcement action against criminals operating within the HKSAR and works closely with Mainland and overseas agencies to curtail the activities of Hong Kong-connected syndicates operating in other jurisdictions.

Organized Crime and Triad Bureau

Investigates complex organised crime and serious triad offences. It pools together resources and expertise from different sources to tackle sophisticated and syndicated criminal activities including money laundering. The assets of criminals involved in non-narcotic related crimes are also identified, restrained and confiscated. It also liaises regularly with Mainland and overseas law enforcement agencies for exchange of intelligence to prevent and neutralise illegal activities.
