PASAY CITY—Former Senator Antonio Trillanes IV stunned the Senate media on May 11, by brandishing a copy of an alleged International Criminal Court (ICC) arrest warrant targeting Senator Ronald "Bato" Dela Rosa. 

The revelation coincided with Dela Rosa’s sudden appearance at the plenary, marking his first time on the Senate floor since vanishing from public view in November 2025. 

Trillanes claimed the document confirms the Hague-based court’s move to take custody of the former police chief, ending months of speculation regarding the Senator’s prolonged absence and legal standing.

The tension escalated further as the Office of the Senate Sergeant-at-Arms (OSAA) presented CCTV footage to the plenary, documenting a potential security breach within the chamber. 

The video shows individuals identified as alleged National Bureau of Investigation (NBI) agents tailing Dela Rosa through the Senate corridors immediately upon his return. 

Senate leadership is now grappling with the dual crisis of an international legal pursuit and the presence of law enforcement agents operating inside the premises, sparking an immediate debate over parliamentary immunity and the sanctity of the institution.
