A man was allegedly attacked by a patched Mongrel Mob member in front on his son during a road rage incident in Hamilton.
A police spokesman said police had received an assault complaint, after the incident on State Highway 1 near Horotiu this morning.
"The victim, a Waikato man, called police from his home to report that he had been attacked by the driver of a car following a traffic altercation."
The man told police he had been dragged from the car and "punched several times" by a patched Mongrel Mob member.
Fairfax Media reported the victim's wife said her husband was spat at, dragged from the car and punched in the face several times.
