A motorcyclist and a sportscar were involved in a high-speed race on a busy dual carriageway, with both vehicles weaving between traffic, just seconds before the biker was killed in a crash, witnesses have told an inquest.

An inquest into the death of a man who died in a road traffic crash is set to go ahead today despite strenuous efforts by the man’s father to have it delayed because he says it was never properly investigated.

Gardaí investigating a fatal road traffic accident in Cork have renewed their appeal for the driver of a black sports car to come forward.
