A sitting Philippine senator wanted by the International Criminal Court for his role in former president Rodrigo Duterte’s drug war took refuge inside the Senate on Monday to avoid arrest by government agents. Senator Ronald Dela Rosa, the country’s one-time police chief, was under the Senate’s protection “in accordance with our rules and Philippine laws”, newly elected Senate President and Duterte ally Alan Peter Cayetano told reporters.“We will allow an arrest under the condition that it is a Philippine court,” he added. The Senate was on “lockdown”, officers told AFP journalists who saw barbed wire and riot police surrounding the compound’s closed gates. Only hours earlier, Dela Rosa – not seen publicly since November – had appeared at the Senate to cast a vote for Cayetano, a move that came just as members of the House of Representatives were impeaching Vice-President Sara Duterte-Carpio.
