A teenager was attacked with a knife by a motorist as he was walking in Nelson.
Police said the incident happened yesterday at between 5.15pm and 5.30pm on the corner of Arapiki and Main Roads in Stoke.
The boy was walking near the intersection when men in a white Toyota driving south along Main Road stopped next to him.
A man got out of the passenger side of the vehicle and cut the teenager's arm with a knife.
He then got back into the car and the driver did a U-turn and drove off in the opposite direction.
