Residents are hiding behind barricaded doors as monkey gang fights create no-go zones for humans. The ancient Thai city has been overrun by a growing population of monkeys super-charged on junk food as locals try to placate the macaques with snacks. A government sterilization campaign is now being waged against the creatures after the epidemic provoked an unexpected change in their behavior. As tourism seized up, so did the flow of free bananas, prodding the macaques to turn to violence. An abandoned cinema is currently the macaques' headquarters. Residents have taken it upon themselves to feed the macaques to prevent clashes.
