I don’t have any backinfo about the video, but the language sounds Brazilian Portuguese to me. The video shows a woman being punished by getting her hands and fingers mashed with a hammer.
I presume the woman was caught stealing, as it’s common for thieves to be punished in the similar manner in Brazil. They fucked her hands up good with that tool. Considering how many fine bones there are in hands, she won’t be stealing anytime soon, nor doing much else for that matter.
Props to Best Gore member @african-angel for the video:
