A wetsuit has saved a 13-year-old boy from serious injury after he was struck by a fishing line that was tied across the Tasman Highway at Scamander on Saturday.
The boy was walking along the Scamander River Bridge footpath at 6pm when a car travelling in the opposite direction hit the deliberately-placed fishing line and pushed it into his upper thigh.
The line cut into the boy's four-millimetre wetsuit in two places, causing minor lacerations and burns to his thighs.
It is not known who tied the line across the bridge.
Scamander surf shop proprietor Dale Matheson said that the wetsuit probably saved the boy from serious injury.
``If the line had cut into bare skin, we'd be looking at a very, very bad cut to the thighs,'' Mr Matheson said.
``The fishing line was tied there specifically to hurt someone.
``I can't understand why someone would commit such an act of stupidity.''
The Scamander Bridge is in a 60km/h zone, with people frequently fishing off the side into the Scamander River.
