Even in relatively isolated developing nations criminals find ways to arm themselves. Below are a number of crude improvised firearms made from regular household stapler guns recently seized by police in Papua New Guinea which are fast becoming a trend.
The example above was seized on the 28th of November from a suspect (shot and killed during the arrest) who was wanted for a string of armed robberies. As is commonly seen, ammunition may be wrapped in tape or a makeshift rim added using wire to allow whichever cartridges are on hand to be retained and fired through an otherwise oversized pipe.
Many of these gunsmiths are rather adventurous in their choice of cartridges.
The last example was used to fire at security guards during an attempted burglary in September.
