Stopped at a checkpoint for riding a motorcycle without a helmet, Genivaldo de Jesus Santos, 38, was forced into the boot of a police car by three police officers, who sprayed pepper spray and teargas into the confined space.
With dozens of bystanders watching – some of them shouting “You’re going to kill him” and warning that De Jesus was mentally ill – the officers kept him in the makeshift gas chamber for 11 minutes and 27 seconds in 2022 in the north-eastern Brazilian state of Sergipe.
