Wild boar have a reputation for being aggressive, and this hunter learned that the hard way.
This hunter arrowed a wild boar in the vitals which should have been the end of the story. However, the pig still had enough fight in it to charge the bowhunter. The hunter was knocked over and obviously very shocked, but he did not sustain any serious injuries. This hunter was lucky he was not seriously hurt as there have been several cases of wild boars injuring and even killing humans.
The lesson here is that the hunt is not over after the shot.
