A Whanganui man attacked an 80-year-old after becoming enraged by a traffic incident.
Ian Dean Peeti was driving along State Highway 3 when his vehicle was involved in an incident with another and it made him so mad he began tailing it.
Peeti, 53, appeared in Whanganui District Court for sentencing on Wednesday.
Judge Christopher Field explained what happened.
"You became enraged at what had occurred, you followed the victim into the carpark of a local business, parked alongside him, approached him and opened the door.
