Amid calls for Dela Rosa's resignation following the death of a South Korean businessman inside Camp Crame, Duterte said Dela Rosa will stay as PNP chief who has his "full trust."

Dela Rosa on his birthday Saturday, wished for erring cops to change their ways amid controversies surrounding the PNP over a spate of reported "tokhang for ransom" incidents.
