Mao Aplasca Biography
Mao Aplasca was born on August 22, 1963, in Maco, Davao de Oro, Mindanao, Philippines. He is a retired Philippine Police Major General. He is best known for his long career in the Philippine National Police, his leadership of the Aviation Security Group during the “tanim bala” controversy, his role as Administrator of the Office for Transportation Security, and his appointment as acting head of the Office of the Senate Sergeant-at-Arms (OSAA) in 2025. Mao Aplasca is 62 years old as of 2026.
Aplasca’s educational foundation did not stop at the academy. He pursued a Master in Development Management at the Asian Institute of Management and a Bachelor of Laws at Jose Rizal University, adding academic depth to a career built on field experience. He also completed the FBI National Academy programme in Quantico, Virginia — one of the most prestigious law enforcement training programmes in the world — along with additional security and intelligence courses abroad. The combination of military training, advanced academic study, and international law enforcement education gave him a professional profile that was notably broad for a career security official.
Now 62 years old in 2026, Aplasca is Filipino by nationality with cultural roots in Mindanao’s Davao de Oro community. He is believed to have a Christian background, consistent with his reported participation in Christian leadership fellowships and values-oriented public service groups, though he has not made a formal public declaration about his religious life. He is married to Maria Rica Acab-Aplasca, known to those close to him as “Cookie,” and both have maintained a deliberately private family life throughout his long public career.
Mao Aplasca Career
Mao Aplasca began his active service shortly after graduating from the Philippine Military Academy in 1987, initially serving in the Philippine Constabulary Special Action Force and regional police units. His early career included field operations, provincial investigations, and security coordination, as well as an international assignment connected to the United Nations mission in Cambodia in the early 1990s — an experience that expanded his perspective on security work beyond domestic operations.
As the years passed and he climbed through the ranks of the Philippine National Police, Aplasca accumulated postings that covered a wide range of responsibilities: Chief of Police, Regional Director for CALABARZON, and Director for Operations at PNP Headquarters. Each role added a dimension to his understanding of how large, complex security organisations function at both the operational and strategic levels. He was consistently described by colleagues as disciplined, strategic, and reform-oriented — qualities that made him a natural fit for roles requiring institutional change as much as operational competence.
His most publicly visible role within the PNP came when he was appointed head of the Aviation Security Group, at a time when Philippine airports were under intense scrutiny over the so-called “tanim bala” scandal — a series of controversies involving airport personnel allegedly planting bullets in passengers’ bags as a form of extortion. His leadership during this period was associated with efforts to reform procedures, restore public confidence, and improve operational accountability across airport security operations. The national attention surrounding the scandal gave Aplasca a prominence he had not previously held outside of law enforcement circles.
After retiring from the Philippine National Police with the rank of Police Major General in 2019, Aplasca moved into civilian government service as Administrator of the Office for Transportation Security (OTS), the agency responsible for airport security, transportation threat management, and national transportation protection systems. His tenure there continued to attract public attention, particularly as debates about airport theft and passenger safety remained active topics in Philippine media. He remained one of the country’s most recognisable security officials throughout this period, even in retirement from uniform.
Mao Aplasca Personal Life
Mao Aplasca has been married to Maria Rica Acab-Aplasca, known as “Cookie,” throughout his public career. The couple has maintained a notably private family life, with very little verified public information available about their children, parents, or siblings. This discretion is consistent with the broader profile Aplasca has cultivated over decades — a public servant who lets his institutional record speak for itself rather than seeking personal visibility through media exposure.
There are no known public controversies concerning his personal relationships. The attention he has attracted throughout his career has been overwhelmingly focused on his professional conduct — security leadership, police reforms, transportation safety, and most recently, his role in the Philippine Senate. His personal life has, by all accounts, remained well outside the spotlight that has periodically surrounded his official responsibilities.
Mao Aplasca Acting OSAA Head
Mao Aplasca’s return to institutional prominence came in 2025 when he was appointed to head the Office of the Senate Sergeant-at-Arms (OSAA) — the body responsible for Senate security, the protection of lawmakers, and the maintenance of order during legislative sessions. His appointment was connected to his relationship with Senator Ronald “Bato” dela Rosa, his Philippine Military Academy classmate. He replaced retired Air Force Major General Rene Samonte, who had been reprimanded by dela Rosa for allowing National Bureau of Investigation agents inside the Senate grounds during a tense standoff related to an International Criminal Court arrest warrant.
“When the OSAA saw that there were NBI agents at GSIS — standing beside the blue guard — the OSAA immediately noticed that they were already geared up, wearing vests and preparing for an operation.” — Palace Press Officer Claire Castro
The circumstances surrounding the handover quickly became one of the most dramatic episodes in recent Philippine Senate history. On the evening that Aplasca assumed effective control of Senate security, gunshots were fired within the GSIS compound, where the Senate is located. The Philippine Senate rents a building inside the GSIS compound, connected to GSIS through a bridge — the key to which is held by the OSAA. NBI agents had arrived at the GSIS building at around 6 p.m. at the request of GSIS President and General Manager Wick Veloso, who sought security assistance amid the tensions surrounding dela Rosa’s potential arrest.
When OSAA personnel saw the NBI agents positioned near the bridge — geared up in vests and appearing prepared for an operation — they approached. According to Palace Press Officer Claire Castro, after the NBI agent identified himself, Aplasca immediately fired a warning shot. The NBI agent fired back. The exchange, described by authorities as warning shots rather than an assault, triggered immediate investigations by the Pasay Police Station in coordination with the Criminal Investigation and Detection Group.
NBI Director Melvin Matibag separately clarified that drilling sounds heard near the Senate door that same evening were related to efforts by GSIS to close and secure the bridge access point, not to any assault operation. Metal cabinets were placed as barriers so that the bridge would no longer be passable.
The incident generated significant national media coverage and raised serious questions about institutional boundaries, security protocols, and the appropriate limits of authority when competing government agencies find themselves in direct confrontation within a single compound. For Aplasca, a man who had spent his career managing exactly the kind of high-pressure security situations that most people only read about, the Senate incident became the defining public moment of his second act in government service.
Conclusion
Mao Aplasca has spent nearly four decades operating in environments where the stakes of a wrong decision are measured not in lost revenue but in lost lives, lost order, or lost institutional integrity. The warning shot fired at the GSIS compound in 2025 may be the moment that many Filipinos will most associate with his name — but it is only one moment in a career that has been shaped, for better and for worse, by a consistent willingness to act when others hesitate.
