Organization of Hong Kong Police  The Hong Kong Police Force (HKPF) is structured into numerous bureaus and units. As a whole, it is commanded by the Commissioner of Police, who is assisted by two deputy commissioners; a "Deputy Commissioner – Operations" supervises all operational matters including crime and a "Deputy Commissioner – Management" is responsible for the direction and co-ordination of force management including personnel, training, and management services. For day-to-day policing (Operations), the Force is organised into six regions: Hong Kong Island; Kowloon East; Kowloon West; New Territories North; New Territories South; and Marine Region. The Force Headquarters (Management) is made up of five departments: Operations & Support; Crime & Security; Personnel & Training; Management Services; Finance, Administration & Planning. Regions are largely autonomous in their day-to-day operation and management matters, and each has its own headquarters, which comprises administration and operation wings, Emergency Units, as well as traffic and criminal investigation units. Each region is divided into districts and divisions and, in a few cases, sub-divisions. Currently, there are 23 districts. The policing of Hong Kong Island, Kowloon and the main towns of the New Territories follows a similar pattern. Responsibility for law and order on the Mass Transit Railway, which runs through most police districts, lies with the Railway District. Railway District based at 2 Siu Yip Street in Kwun Tong is responsible for patrols on the MTR. Police Force operational matters are coordinated by the Operations & Support Department. Land Operations and Support are divided into six regions, whereas marine matters are managed by the marine police—organised as one Marine Region. Each land region comprises two wings, the operations wing and support wing, and a traffic headquarters (which is part of the operations wing). The department is charged with the formulation and implementation of policies, the monitoring of activities and the efficient deployment of personnel and resources. Operations Wing coordinates counter-terrorism, internal security, anti-illegal-immigration measures, bomb disposal commitments and contingency planning for natural disasters—they are also responsible for the Police Dog Unit. The Operations Wing consists of three sections: The Operations Bureau, the Police Tactical Unit, and the Explosive Ordnance Disposal Bureau. Operations Bureau comprises the Operations Division, the Counter-Terrorism and Internal Security Division, and the Key Points and Search Division which includes the Police Dog Unit. It deals mainly with the staffing of operational matters which include the formulation and dissemination of relevant Force orders, boundary security, deployment of resources, and liaison with the Hong Kong garrison.
