The National Bureau of Investigation (NBI) (Filipino: Pambansang Kawanihan ng Pagsisiyasat) (PKP), is an agency of the Philippine government under the Department of Justice, responsible for handling or solving sensational cases that are in the interest of the nation.



The National Bureau of Investigation (NBI) saw its inception on November 13, 1936 upon approval of Commonwealth Act No. 181 by the legislature. It was the brainchild of the late President Manuel L. Quezon and Jose Yulo, then Secretary of Justice.

Tasked with organizing a Division of Investigation or DI patterned after the United States Federal Bureau of Investigation were Thomas Dugan, a veteran American police captain from the New York Police Department and Flaviano C. Guerrero, the only Filipino member of the United States Federal Bureau of Investigation.[1]

On the basis of stiff physical, mental, and moral standards, 45 men were selected as agents from among 300 applicants. To complement this investigative force was a civilian staff composed of doctors, chemists, fingerprint technicians, photographers, stenographers, and clerks.

During the Japanese occupation, the DI was affiliated with the Bureau of Internal Revenue and the Philippine Constabulary known as the Bureau of Investigation (BI). Subsequently, during the post-liberation period, all available DI agents were recruited by the US Army CIC as investigators.

Since then, the Bureau assumed an increasingly significant role. Thus, on June 19, 1947, by virtue of Republic Act No. 157, it was reorganized into the Bureau of Investigation. Later, it was amended by Executive Order No. 94 issued on October 4, 1947 renaming it to what it is presently known, the National Bureau of Investigation (NBI).

NBI's motto is: Nobility, Bravery and Integrity ...efficient law enforcement in the pursuit of truth and justice.

The Intelligence Service, NBI

The Intelligence Service (formerly known as the Domestic Intelligence Services; Domestic Intelligence Division; Intelligence Section) is the security service arm of the Bureau which undertakes internal security operations against terrorist elements and large organized crime groups who are identified as threats to the State as well as undertake internal security operations and investigation on suspected corrupt government officials or persons deemed or identified as a security threat. It is also mandated to undertake and supervise the security training and education of government, police and military personnel (upon their agency request)on matters relating to intelligence and security and when call upon, conduct security survey and risk assessment of government (and at times, private) infrastructures classified as critical in nature.

IS-NBI operational divisions from time to time are called on by the Bureau management to assist the Special Investigative Services (SIS) in the solution of a number of the high profile-complex crime cases handled by the Bureau during the past several years.

The Operational Divisions of the Intelligence Service-NBI are as follows:

  • Background Investigation Division (BID) - Transferred to the Intelligence Service as per Administrative Order No. 10, series of 2009
  • Counter Terrorism Unit (CTU) - formerly the Anti-Terrorism Division (ATD)
  • Counter Intelligence Division (CID)
  • Criminal Intelligence Division (CRID)
  • Field Operations Division (FOD)
  • Intelligence Special Operations Division (ISOD)
  • Research and Analysis Division (RAD)
  • Reaction, Arrest and Interdiction Division (RAID) - Transferred to the Intelligence Service as per Administrative Order No. 11, series of 2009
  • Security Management Division (SMD)

As a general rule, the NBI endeavors to bring the malefactors of society alive before the bar of justice. However, if a legitimate law enforcement operation is carried out by the NBI and is met by some form of resistance from the targeted criminal subject(s), NBI agents are trained to utilize appropriate amount or corresponding use of force in accordance with the existing NBI Rules of Engagement (ROE).

At present, select operatives of the IS-NBI are on detached service with the Task Force Judiciary Protection (TFJP) specifically created to undertake the protection, risk assessment, investigation and security training of members of the Judiciary that are:

1. Assigned to high risk areas;

2. Received death threats in connection with high risk or heinous crime cases filed in their respective courts;

3. Actual victims/survivor of violent action intended to kill, maim or wound them;

4. Assigned to courts which have been the subject or has experienced violent attacks against one of its members, clients or visitors;

IS operatives assigned with the TFJP also undertakes overt and covert security inspections of Hall of Justices in various parts of the country in order to gather data for an ideal security protocol for the lower courts. This assignment is undertaken with the guidance and supervision of the Committee on Security of the Supreme Court formerly chaired by Associate Justice, Hon. PRESBITERIO J. VELASCO, but now under the helm of CHIEF JUSTICE REYNATO S. PUNO

The Intelligence Service is also currently entrusted with securing the persons of a number of High Profile Subjects (HPS) mostly state witnesses believed to be High Risk Targets.

The IS-NBI also maintains close working relationship with its domestic counterparts and at times undertake coordinated security operations against terrorist elements with augmented manpower complements from these units.
