SPCA investigates possum punch video

The SPCA is investigating after a video surfaced on Facebook of a man punching a possum in the head. In the video the man can be seen approaching a possum sitting on a fence post - he then delivers a vicious right hook to the possum's face, knocking it off the post and to the ground. It's thought the incident took place in Taranaki. The SPCA's chief executive is Andrea Midgen. She talks to Guyon Espiner.
