The Philippine National Police - National Capital Region Police Office was established as the Philippine Constabulary Metropolitan Command on July 5, 1967 through Executive Order No. 85 of then President Ferdinand Marcos. It was founded as the Special Strike Force of Police Forces in the area which would later be known as Metro Manila. The establishment was a response to the increase of criminality in then existing four cities and thirteen municipalities in the area. The METROCOM was tasked to conduct operations against threats to national security in the Metropolitan Manila area as well as support to the local police forces of the localities in their suppression and prevention of crime. The Metropolitan Police Force was later established on March 21, 1974 through Presidential Decre No. 421 issued by then-President Ferdinand Marcos. The decree consolidates the police, jail, and fire departments in the Metropolitan Manila area and placed them under the Commanding General of the METROCOM which served as head of the unit.
As PC Capital Region Command
Following the People Power Revolution of February 1986 which ousted Marcos as president, the PC METROCOM was renamed as the Philippine Constubulary Capital Region Command. The Philippine Constubulary itself would be abolished through Republic Act 6975. issued by then President Corazon Aquino in December 1990. The Philippine National Police was established as in PC's place. Under the Republic Act 6975, two regional offices were created for Metro Manila, North CAPCOM and South CAPCOM. These offices were deactivated in April 12, 1993.
As PNP NCRC and PNP NCRPO
In 1994, the PNP CAPCOM was renamed as the National Capital Region Command and was renamed again in June 1996 to its current name, the PNP National Capital Region Police Office through NAPOLCOM Resolution No. 96-058.
Divisions
The PNP NCRPO has five police districts under it. Among the localities in Metro Manila, Manila and Quezon City are the only localities to have a dedicated police district.
The holding of a mañanita for NCRPO's chief Debold Sinas amidst the COVID-19 pandemic in Metro Manila was criticized for breaching quarantine regulations. A mañanita is a customary celebration in the police where senior officers are greeted by their personnel in the early morning of their birthdays. The national police has filed charges against Sinas over the event, for violation of existing regulations on social distancing and mass gatherings though Sinas keeps his post due to "emergency situation" caused by the pandemic.
