A Dubuque, Iowa man says his friend's raccoon went crazy before it attacked him.

Police say Steven Hines called police early Tuesday morning to report that he had been bitten.

Hines had agreed to watch the animal for a few days and decided to let it out of its cage for a while. Police say that Hines told officers that when he opened the cage the animal "went crazy" and scratched and bit at his hands and arms.

Police say that when they arrived, the raccoon was locked in its cage and appeared calm and tame.

The animal was taken to the Humane Society to be examined by a veterinarian. Hines refused medical treatment.
