A retired Philippine police officer says President Rodrigo Duterte, when he was a city mayor, ordered and paid him and other members of a so-called liquidation squad to kill criminals and opponents, including a kidnapping suspect and his entire family and a critical radio commentator.

Human rights lawyers who presented Arthur Lascanas at a news conference Monday said his allegations could be grounds for impeaching Duterte. There was no immediate comment from Duterte or his office.

Lascanas comments come after he denied at a Senate hearing last year that he was involved in any extra-judicial killings in southern Davao city. He said Monday he was bothered by his conscience and decided to reveal his role.
