Mad stray dog problem in locality.

A stray dog has gone mad in our locality since yesterday. And in just over 24 hours, it has already bitten a kid, a woman, another stray dog and severely injured a cat. The kid's condition was so severe that she had to be rushed to the hospital immediately. Although she's stable now, the dog has bitten off a large amount of flesh from her legs. What can be done in this situation? Will the municipality help? If so, how to contact them ? The people don't seem to care at all. They always feed these strays even though these are a menace to the society. The kid's incident occurred yesterday afternoon and I saw someone feeding biscuits to the dog in the evening. This is the severity of negligence among the people.
