A drink-driver who mowed down and killed a motorcyclist after a Sunday-morning vodka binge has been jailed for nine years.

Zbigniew Zawistowski, 32, ploughed into 55-year-old father Kevin Jenkins in St Peter's Road, South Croydon, before leaving him for dead on June 9 last year.

Croydon Crown Court heard this week he had drunk enough vodka to "significantly influence" his driving at a friend's house in nearby Dean Street that morning and was already disqualified for drink-driving.

Zawistowski, of Robins Court, Birdhurst Road, South Croydon, was seen driving erratically in his Volkswagen Touareg after leaving his friend's house.

After nearly colliding with two pedestrians, he turned right into St Peter's Road into the path of dad-of-two Mr Jenkins, of Sylvan Close, Selsdon.

Zawistowski and his passenger both abandoned the 4x4 and fled on foot without calling an ambulance or any attempt to help.

Computer software expert Mr Jenkins, who had two sons, was pronounced dead at the scene from multiple injuries. Witnesses described seeing the mangled remains of his bike strewn across the road.

Zawistowski handed himself in to police three days later, when evidence of the alcohol was out of his system.

Police learned he had continued to work as a heavy-goods vehicle driver despite being disqualified for drink-driving in March 2012, taking out insurance in his brother's name to conceal his identity.

Zawistowski pleaded guilty on Tuesday to causing death by careless driving while under the influence of drink, causing death by driving while disqualified, causing death by dangerous driving while uninsured and fraud by failing to disclose information.

He was jailed for a total of nine years yesterday and disqualified from driving for seven years.

Sergeant Stephanie Watts, from the Metropolitan Police's Roads and Transport Policing Command, said: "Zawistowski paid utter disregard to motoring law and got behind the wheel having drunk alcohol, resulting in the tragic death of a fellow road user.

"We hope today's sentencing is a deterrent to those who believe it is safe to get behind the wheel while intoxicated, especially over these summer months."
