The Philippine justice chief ordered authorities on Thursday to enforce an International Criminal Court warrant for the arrest of a senator wanted on an alleged crime against humanity. He warned that anyone helping the senator evade a nationwide hunt would face criminal charges.

Senator Ronald Dela Rosa “is a fugitive from justice”, Justice Secretary Fredderick Vida said in a news conference. “He should be brought to the ICC to face the charges.”

Dela Rosa is a former national police chief who enforced then-president Rodrigo Duterte’s bloody crackdown against illegal drugs that killed thousands of mostly petty suspects. The killings alarmed Western governments and human rights groups.

Duterte, who was president from 2016 to 2022, was arrested last year and flown to The Hague, where he is on trial at the ICC on charges of crimes against humanity.

Dela Rosa had petitioned the Philippine Supreme Court to block his ICC warrant, arguing that the country no longer belongs to the global court. But the court refused that petition.

Vida said that authorities have leads on Dela Rosa’s whereabouts, but he refused to elaborate. He warned that anyone helping the senator evade arrest would be criminally charged.
