The La Union Police Provincial Office, formerly the Military Police Command (PA) stationed at Bacnotan, La Union was organized on 01 January 1946 with CAPTAIN TOMAS M LAZARO, PC as the Provincial Commander. On 01 July 1948, CAPTAIN LAZARO was promoted to LIEUTENANT COLONEL, and subsequently retired with CAPTAIN BRUNO CALLEJO, succeeding him. The Headquarters moved from Bacnotan, La Union to its present location at Brgy. Carlatan, San Fernando, La Union where many great military leaders came to serve with distinct honor and achievements.

             The organization had changed Command leadership for forty nine (49) times beginning from the time of CAPTAIN LAZARO way back in 1946. On 16 January 2006, PSSUPT FRANKLIN JESUS BERNARDINO BUCAYU assumed office and thus became the 49^th Provincial Director of the province of La Union up to present.

             The combined efforts and resourcefulness of these military leaders who served this Office brought about a model camp in Region-1 where disciplined Constabulary / Philippine National Police Officers and men now live with great sense of integrity and servitude.

             The camp is located in sprawling place of prime real state located East of China sea at Brgy Carlatan, City of San Fernando, La Union. Upon entering the camp, one will notice the Guard House where visitors get proper guidance and direction from the duty guard in uniform. Along the road are offices of tenant agencies that have come to call this camp a second home away from home. We have the 1^st Regional Criminal Investigation and Detection Group (1^st RCIDG), National Intelligence Coordinating Agency (NICA), Regional Traffic Management Office (RTMO-1), Philippine Drug Enforcement Agency (PDEA RO-1) and Regional Intelligence Office (RIO-1).

             The camp of the Philippine Constabulary Headquarters, now the Philippine National Police Office in the province of La Union was named “Camp Diego Silang” effective 13 July 1988 pursuant to general Order Nr. 55 565, GHQ, AFP dated 18 Jul 1978, as a fitting tribute to a man who sacrificed his life in search for reforms in order that his countrymen will enjoy the blessings of democracy and freedom. 

            Further, inside camp is the Office complex where the personnel of this Office tirelessly strive to accomplish effectively the mission it has been given. With this complex are found the Offices building, the PD quarters, the Signal/Communication building, the Provincial Mobile Group Office, the PNP Social Hall, the Motor pool building, Officer’s quarters and the Camp Chapel. 

            In front of the Office building is the training and parade ground of the Command. Within its 3.9 hectares area are various athletic courts where men and women of this Office can unwind and participate in their favorite sports like basketball, lawn tennis and golf. 

            It is within this environment that men and women of the La Union Police Provincial Office do their daily duty of maintaining peace and order in the province and help the general task of nation-building.
