Philippine senator Ronald "Bato" Dela Rosa is holed up inside the Senate building in Manila after evading arrest on an International Criminal Court warrant charging him with crimes against humanity for his role in former president Rodrigo Duterte's deadly drug war. Dela Rosa — who served as chief of the Philippine National Police during the height of the anti-drugs campaign from 2016 to 2022 — was caught on security camera footage being chased up flights of stairs by National Bureau of Investigation agents after arriving at the Senate on Monday. He narrowly escaped detention, and police later confirmed they would not attempt to arrest him while he remained under the Senate's protective custody.
The ICC confirmed on Monday that the arrest warrant, issued confidentially on 6 November 2025 by the all-women judges of Pre-Trial Chamber I, had been unsealed. It charges Dela Rosa as an "indirect co-perpetrator" in the crime against humanity of murder, linked to the killing of at least 32 people between July 2016 and April 2018. Prosecutors say the broader drug war, which Dela Rosa helped design and implement, killed tens of thousands of suspected drug users and dealers. Duterte himself has been in ICC custody in The Hague since March 2025, after the same chamber confirmed charges of crimes against humanity against him in April.
Dela Rosa had largely disappeared from public life for months after rumours of a looming warrant first circulated last year. He returned to the Senate on Monday specifically to cast the deciding vote in a leadership vote that installed his ally, Senator Alan Peter Cayetano, as the new Senate president. That move proved strategically significant: Cayetano promptly placed the chamber on lockdown and told reporters he would only honour arrest warrants issued by a Philippine court. His lawyers have asked the Supreme Court to block the ICC warrant on the grounds that no valid local judicial order exists. On Tuesday morning, Dela Rosa urged supporters gathered outside the building to "keep vigil" until the court rules.
The episode is unfolding amid a fierce political feud between the Duterte and Marcos dynasties, whose electoral alliance collapsed after the 2022 elections. Earlier on the same day as Dela Rosa's flight through the Senate corridors, the lower House of Representatives — dominated by allies of President Ferdinand Marcos Jr. — voted to impeach Vice-President Sara Duterte, Rodrigo Duterte's daughter, for a second time. Dela Rosa made a pointed appeal directly to Marcos, warning the president: "We don't know — one day you might face the same situation. You will feel what I feel right now."
The standoff raises fundamental questions about the limits of legislative privilege and the Philippines' obligations under international law. While Senate leaders argue longstanding precedent bars arrests within the legislature, legal experts say such courtesies have limits and may not override an internationally issued warrant. The Philippines formally withdrew from the Rome Statute — the ICC's founding treaty — in 2019, but ICC judges ruled last month that this withdrawal does not apply retroactively to alleged crimes committed while Manila was still a member, clearing the path for Duterte's trial and now placing Dela Rosa squarely in the court's reach.
