Philippine President Rodrigo Duterte on Tuesday threatened to kill corrupt police, including those accused of involvement in illegal drugs and other crimes, in an expletives-laden encounter on live TV, AP reported.

More than 100 policemen, many of them facing administrative and criminal complaints including rape, kidnapping and robbery, were escorted to the presidential palace to meet Duterte, police officials said.

The national police, which Duterte once called “corrupt to the core,” have been undergoing an internal cleansing since they were removed twice from the president’s crackdown on illegal drugs last year due to reports of abuses. Duterte later allowed them to rejoin drug raids, partly because the small lead anti-narcotics agency lacks personnel and firepower to quell the drug menace.

“If you’ll stay like this, son of a bitch, I will really kill you,” Duterte told the policemen in the dressing-down broadcast by local TV networks.
