WA man shoots at moving car

A man shot at a moving car south of Perth, almost hitting a three-year-old boy in the back seat, WA police say.

A woman was driving from Dwellingup to Boddington on Friday morning when she passed a man in a bush, who shot at the car and pierced the rear passenger door near where the boy was sitting.

The man, who is described as between 30 and 40 years old, about 185 cm tall and with tanned skin and messy blonde-brown hair, hasn't been found.
