Police took Rodrigo Duterte into custody on orders of the ICC, which has been investigating the massive killings that happened under the former president’s deadly crackdown against illegal drugs.

MANILA, Philippines (AP) — Philippine police arrested former President Rodrigo Duterte in Manila on Tuesday and sent him by plane to the Netherlands to face charges of crimes against humanity at the International Criminal Court, President Ferdinand Marcos said.

The global court in The Hague had ordered Duterte’s arrest through Interpol after accusing him of crimes against humanity over deadly anti-drug crackdowns he oversaw while in office, Marcos said in a late-night news conference. Duterte had been arrested at the Manila international airport Tuesday morning when he arrived with his family from Hong Kong.

Walking slowly with a cane, the 79-year-old former president turned briefly to a small group of aides and supporters, who wept and bid him goodbye, before an escort helped him into the plane.

His daughter, Vice President Sara Duterte, said she sought entry to the airbase where her father was held but was refused. She criticized the Marcos administration for surrendering her father to a foreign court which currently has no jurisdiction to the Philippines.

Marcos said Duterte’s arrest was “proper and correct” and not an act of political persecution, since the Philippines is a member of Interpol.
