A banned drink-driver who ran over a teenage boy then told him "your problem, not mine" before driving off has been jailed.

Jan Kozlowski, 40, became the first person in Scotland to be jailed under new road traffic laws designed to clamp down on banned drivers.

He admitted causing serious injury to a 15-year-old boy, who cannot be named for legal reasons, while driving when disqualified.

Dundee Sheriff Court heard Kozlowski was handed a road ban on June 2 last year after admitting a drink-driving offence.

That was his second similar conviction, having previously been convicted of being in charge of a car while drunk.

Kozlowski, a labourer, was back behind the wheel just days later, driving his work van having failed to tell his employers of his ban.

At 6.20pm on July 9, he was driving on Pitkerro Road, Dundee, when he ploughed into the boy as he was crossing the road with friends.

Fiscal depute Eilidh Robertson said: "The boy stepped out between parked cars where he was struck by the motor van being driven by the accused.

"The accused did not swerve or sound his horn. He began to brake once hitting the boy, who remained on the bonnet of the van until the van came to a stop and he fell on to the roadway.

"The boy's friends said they were under the impression the accused was speeding. The boy was helped on to the pavement.

"The accused and his brother, who was a passenger, got out and approached.

"The accused assisted in helping the boy to his feet but said 'your problem, not mine' before getting back in his vehicle and driving away.

"A passer-by called police and an ambulance. The boy was taken to Ninewells Hospital where an x-ray confirmed a broken ankle.

"He was operated on and had his ankle reset using three metal screws which will stay in permanently.

"The fracture was through a growth plate so he may have problems with growth of that leg in future and may require further surgery."

Kozlowski, a prisoner at HMP Perth, pleaded guilty on indictment to a charge of causing serious injury while driving while disqualified.

Defence solicitor Ross Donnelly said: "He accepts he should not have been driving in the first place. The starting point is that he was already disqualified.

"I'd have to accept his actions after the incident bore him no credit."

Sheriff Tom Hughes jailed Kozlowski for a year and a half and banned him from the roads for five years.

He said: "This is a serious matter. You had been driving on the roads while ordered not to do so by the courts."
