Monkeys at a brazillian zoo attacked and injured Joao Leite dos Santos who decided to swim in there enclosure, stating that he wanted to play with the monkeys. The man told globo tv that he was under the influence when he decided to jump into the water.
The man was under the influence and invading what little territory they had...he had it coming to him. I'll be surprised if he's not charged for the incident as well.
