The police report was clear. Anti-drug officers shot and injured three men in one of the Philippine capital's poorest districts, then "rushed" them to hospital where they were pronounced dead on arrival.

But security camera footage tells a different story of what happened just after midday on Oct. 11 in Barangay (district) 19. It shows that police took at least 25 minutes to haul away the men they had shot. The victims show no signs of life; police are seen carrying them by their arms and legs and loading their limp bodies onto pedicabs to take them to hospital.

The footage casts new doubts on the official accounts of police killings in President Rodrigo Duterte's 17-month war on drugs.
