A chase ensued where McCaugherty reached speeds of up to 110mph.
Driving with the headlights off, he drove through red lights in the city centre and hit Mr Subedi at 90mph.

McCaugherty was arrested by police on 30 March when he was seen driving another stolen car.
Judge Mark Wall QC told McCaugherty: "You showed a total disregard for the safety of others who were in great danger because of your actions."

He pleaded guilty to causing death by dangerous driving, assault by beating, making off without payment, dangerous driving, possessing a controlled class B drug, perverting the course of justice and taking a conveyance without a property.
