(CNN) President Rodrigo Duterte has called for a total overhaul of the Philippine National Police in the wake of the alleged brutal killing of a South Korean businessman by corrupt police officials. "Cleanse your ranks. Review their cases. Give me a list of who the scalawags are," Duterte said in a press conference late Sunday night. Last week, Duterte apologized to South Korean investors and South Korean Ambassador to the Philippines, Kim Jae-Shin, for the murder of Jee Ick-joo and promised swift retribution. "I am very sorry for that sordid incident. But I can assure you; policemen -- I will not let you get away," he said according to CNN Philippines.Duterte to dissolve anti-drugs units within the Philippines policeSouth Korean businessman allegedly kidnapped and murdered by rogue cops
