A Brazilian father-of-three has died in a gruesome freak accident after he was sliced by a razor-sharp fighter kite string while on the way to visit his daughter.

Auriel Missael Henrique, 41, was riding with his wife on a motorcycle through the town of Duque de Caxias in northern Rio de Janeiro when tragedy struck on Tuesday.

Out of nowhere, the pair collided with what looked like an innocent string dangling across the road.

But this wasn't just any string - this was a lethal thread from a fighter kite coated in glue and powdered glass, known locally as linha chilena.

As the motorbike zoomed down the road, Auriel's neck became entangled in the deadly cord, splitting his throat open and leaving him critically injured and bleeding on the street.
