A former senior Philippine police official says President Rodrigo Duterte has been photographed with two Chinese men involved in illegal drugs and sent a report to warn him about the two.

Dismissed Senior Superintendent Eduardo Acierto told a news conference late Sunday that he's unaware what government action has been taken after he submitted his report about the Chinese men to top police officials starting in December 2017. Instead, Acierto said he's now facing illegal drugs complaints and has been the target of drug threats that forced him to go into hiding recently.

Philippine Drug Enforcement Agency Director General Aaron Aquino says he received Acierto's report and the allegations against the Chinese are being validated.
