William Singalargh, 27, of New Zealand's North Island, was arrested for assaulting a 15-year-old boy with a hedgehog. He apparently hurled the animal at the boy. From The Daily Telegraph:
"It hit the victim in the leg, causing a large, red welt and several puncture marks," Senior Sergeant Bruce Jenkins said...Link (Thanks, Sean Ness!)
It was not known whether the hedgehog was dead or alive when thrown on February 19, but it was dead when collected as evidence.
