National Security Department

Biodata

History

Origins as the Security Department

The Security Department was created after the disbanding of the former Political Department, inheriting its political assignments and oversight responsibilities. Its founding purposes also included cultivating officers loyal to the Motherland and removing foreign influence from the Police Force 228 468.

Number One, Sir Hui, personally supervised the department. Under Zhou Quan, it accumulated authority through major investigations, political assignments, and internal purges. Its unusually broad responsibilities earned it the unofficial description of a “miniature Police Force” 468.

Its first authorized staffing expansion followed the abolition of the Interpol Asia-Pacific Regional Bureau. Before its conversion into NS, its principal units were the Criminal Operations Division, Internal Investigations Branch, and Liaison Affairs Division 491 492.

Establishment and Expansion

The National Security Law initially changed the department’s legal foundation more than its practical jurisdiction: the former Security Department already possessed extensive authority over security and public-order cases 499 505.

By the later DOA investigation, its subordinate units substantially exceeded the size of equivalent units elsewhere at headquarters. Expansion regularized that growth while opening promotion opportunities for its command personnel 933 972 977 978.

Authority and Jurisdiction

• Broad investigative remit: NS can handle incidents involving threats to public order or national security. Its jurisdiction overlaps with specialist police departments and extends to cases those departments cannot undertake 499 531.
• Fundamental mission: Preventing foreign forces or other hostile actors from undermining Hong Kong Island’s sovereignty takes precedence over ordinary criminal investigation 675.
• Highest statutory operational priority: Other departments are expected to protect NS operations even when doing so delays their own enforcement work 585 838.
• Special procedures: Under specified circumstances, the National Security Law permits operations outside the normal procedures followed by other Hong Kong Government law-enforcement departments 675.
• Supervisory standing: When NS intervenes in another police unit’s work, its role can be one of inspection and supervision rather than equal departmental cooperation 654.
• Cross-agency scrutiny: Its investigations can extend to government officials and personnel in the Marine Police, Customs, and Immigration Department 675 718.
• Emergency powers and reporting: Zhou Quan could initiate Operation Sharp Sword and raise the Police Force’s alert level by administrative order, but still had to report afterward to the Security Bureau 706 721.

Chain of Command and Secrecy

• During Zhou Quan’s direct command, Number One was NS’s sole direct superior within the Police Force. Neither the Operations DCP nor Management DCP could command it 630.
• Its purpose also involved answering to Hong Kong Government leadership and authorities above that level, beyond ordinary departmental administration 671.
• The Operations and Management Deputy Commissioners lacked clearance for its S-class intelligence archive. Even Number One could not simply inspect those files directly, although an explicit order from him still had to be obeyed 746.
• After the later restructuring, Luo Danian handled national security at the broader level, while Kong Chi Lap received day-to-day authority over NS 984 985.

Organization

Senior Leadership

Three Main Departments

The millennium reorganization established three principal departments and nine divisional units. The later restructuring assigned an Assistant Commissioner post to each principal department 572 982.

Capabilities and Training

Tactical Operations

• Operations Security personnel are formally established paramilitary special police, selected from across the Police Force 602 608.
• Zhou Quan’s rotational training program began during the Security Department period and continued after the upgrade to NS 514.
• The department favors superior firepower rather than sending officers with revolvers against heavily armed criminals. During the DC-8 operation, concern for the weapon itself restricted the use of rifle-mounted grenade launchers 794.
• Its elite action-group syllabus requires officers to exploit a flashbang’s approximately three-second optimal effect window. The DOA Building assault secured victory within that window and complete control in roughly ten seconds 920.

T Squad and the Special Combat Group

• Original T Squad: A temporary elite formation assembled under Zhou Quan’s direct command or with his approval; described as NS’s operational backbone 602.
• Later twelve-man Special Combat Group: Established within T Group and trained according to the methods used for the original T Squad 920.
• Dedicated mission role: The twelve-man team performs no investigative work; its routine consists of missions and preparation for missions 920.
• Continued deployment: T Squad remains an operational asset after the branch restructuring and participates in the Four-Country, Five-Region Joint Anti-Drug Operations 1004.

Intelligence and Technical Support

• The Intelligence Group’s systems connect to intelligence resources across the Police Force, Mainland China, and overseas law-enforcement agencies 575.
• Professional intelligence communications staff operate highly encrypted channels designed to resist interception and probing 513.
• Officers can use street CCTV to identify and track suspects, providing live directions to field teams 741.
• Zhou Quan personally trained technical specialists whose expertise includes computer operations and the restoration of tampered surveillance footage and recordings 656 807.
• The Intelligence Group manages NS’s internal network and supervises the Police Force’s internal network 972.
• The Operations Command Centre is described as the Police Force’s most technologically advanced departmental command facility 666.

Personnel Standards

• Every officer, including the lowest-ranking personnel, undergoes quarterly review and assessment 635.
• Officers who fail competency standards for four consecutive quarters are transferred out 676.
• Conduct failures can result in demotion and transfer or outright dismissal. By the Cold War investigation, no NS officer had been dismissed for failing a personal-conduct review 676.
• Transfers into any NS section receive at least acting Sergeant rank until formally promoted or rotated elsewhere 782.
• All personnel, including administrative staff, are authorized to carry weapons 741.
• Internal failings can bring accountability upon both the director and the relevant group deputy commanders 635.

Investigative Limitations

• Commercial crime was initially a weak area: both NS generally and its Intelligence Group had concentrated more heavily on criminal offenses 574.
• Political investigations still required attention to manpower, duration, secrecy, and potential government opposition. Zhou Quan imposed a one-year working window on the investigation preceding the Cold War Incident 675.
• Promotions depended on authorized posts and formal procedures. Before successive expansions, management officers could not simply advance without a vacancy or an upgraded establishment 556 632.

Facilities and Equipment

• Operations Command Centre: Coordinates surveillance, intelligence, tactical deployments, and multi-department operations at Tai Kwun 706 804.
• Secret Intelligence Operations Center: Located in Zhou Tower and first brought into full operation for the DOA investigation. Its personnel retain overt NS identities rather than belonging to a separate fixed roster 915.
• Soundproof operations conference room: Part of the Zhou Tower facility, used for joint operational planning 915.
• S-class top-secret archive: Stores highly restricted intelligence files, including agent dossiers 746.
• Safe houses: Used for protected witnesses and restricted interrogations; Mr. Dong is ordered transferred to West A Safe House 734 972.
• Stealth armoured vehicles: Each Action Group receives two. Documented models include BMW sedans and Land Rover multipurpose vehicles 548.
• Vehicle requisition authority: NS can obtain special police vehicles from the wider Police Force when required 548.
• Overseas deployment resources: Teams travel with specialized clothing and precision equipment aboard chartered aircraft, while weapons authorization is arranged separately 602.

Operational Culture

Under Zhou Quan, NS combines internal loyalty with cooperation toward other police units. Its officers are described as friendly to colleagues, willing to share investigations, and prepared to recommend outside personnel for commendations rather than monopolize credit 538.

That approach does not prevent it from asserting command when necessary. Officers avoid casually abusing their standing, but distinguish ordinary cooperation from operations where NS authority must be established 654.

The department also forms the core of Zhou Quan’s power base. Almost all its management officers were personally promoted and cultivated by him, and many later moved into senior positions across the Police Force 630 984.

• Credit-sharing in practice: During the Fenghua International case, Zhou Quan ordered that the Criminal Intelligence Bureau and Commercial Crime Bureau retain the credit for their prior work 651.
• Career development: Zhou Quan deliberately used press appearances to build trusted officers’ public standing and future promotion prospects 516.
• Continuity of leadership: Senior officers pass their superiors’ care for personnel down to their own teams; Jing Jinxian’s relationship with his subordinates is a documented example 1014.
