Two men from Auckland's North Shore have been arrested by police following separate road rage incidents which occurred last month.
In both attacks, the victims were knocked out after minor traffic incidents.
A 29-year-old was arrested today by Waitemata North Shore detectives after a "minor" incident on Boxing Day in Wairau Valley.
In an unprovoked attack, the man allegedly confronted a 45-year-old man and punched him several times in the head, knocking him unconscious.
