Investigation underway after Dunedin streetstocks race incident

An investigation is underway after a car catapulted over a four metre high safety fence during a streetstocks race at a Dunedin speedway track, narrowly missing spectators. Video of the incident at the Beachland Speedway track on Friday shows a gnarl up on a bend with two cars colliding at speed. One is sent into a barrell roll, while other appears to be thrust into air by the force of the rolling vehicle. Speedway New Zealand Ricky Bolton speaks to Lisa Owen.
