MANILA police have urged students and school authorities to file formal complaints and cooperate with investigators to help identify those behind a series of bomb threats targeting universities in the city.

Manila Police District (MPD) District Public Information Office chief Major Philipp Ines made the appeal, warning that investigations could face difficulties without the cooperation of those affected.

Ines stressed that bomb threats should not be taken lightly, as they prompt security operations and cause fear and disruption among students, teachers, school personnel, and parents.

The recent incidents involved the University of the East (UE), the University of Santo Tomas (UST), and De La Salle University (DLSU).

According to initial information, the threats at UE and UST were reportedly discovered in written notes left inside school restrooms, while DLSU received a threat through email.

Ines acknowledged the challenges of identifying those responsible, particularly when handwritten threats are left in areas where closed-circuit television (CCTV) cameras cannot be appropriately installed.

He said, however, that the notes could serve as evidence, while online threats were being investigated with the assistance of anti-cybercrime personnel.

The MPD is also coordinating with school administrators, police commanders, and school security personnel to strengthen its response to such incidents.

Ines said some threats could potentially be made by students seeking to suspend classes for personal reasons. However, he did not identify any confirmed suspects in the incidents discussed at the forum.

He warned that those found responsible could face legal consequences. Parents or guardians of minors may also be held accountable, depending on the applicable laws and circumstances.

The police official urged students and other individuals with information about the incidents to come forward, assuring them that their identities and the information they provide would be treated confidentially.

He also encouraged the public to report genuinely suspicious activities through the MPD’s official social media accounts or the unified 911 emergency hotline.

Ines reiterated that the MPD was taking the threats seriously, emphasizing that the safety of students and teachers remains a priority.

He called on school authorities to submit the necessary information and documentation to help investigators pursue the cases and hold those responsible accountable.
