Why did GSIS ask NBI, not PNP, for additional security? Jonvic Remulla answers | ANC May 21, 2026 • CNN Philippines The Philippine National Police investigation into the May 13 Senate gunfire incident has concluded that all bullet holes found in the building came from shots fired inside the premises. The PNP and the Department of the Interior and Local Government presented their findings, along with CCTV footage, during a Palace briefing on Tuesday. The results contradict earlier claims suggesting that shots may have originated from outside the Senate. Investigators said the evidence clearly shows the exchange happened within the building, prompting further scrutiny of security lapses and the sequence of events that led to the chaos. Separately, Cavite Governor Jonvic Remulla addressed questions on why the Government Service Insurance System requested additional security from the National Bureau of Investigation rather than the PNP. Remulla explained that GSIS made the request based on operational needs and existing coordination arrangements with the NBI for specific protective duties. He noted that agencies are free to tap the most appropriate law enforcement body depending on the situation, adding that such decisions do not reflect any lack of confidence in the PNP. The incident has renewed calls for tighter security protocols in government facilities. Officials said the ongoing review aims to prevent similar disturbances and ensure the safety of lawmakers and staff. Watch the full video below:
