A banned drink-driver ran over a teenage boy then told him "your problem, not mine" before fleeing the scene.

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

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

Dundee Sheriff Court heard that 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 while driving his work van having failed to tell his employers of his ban.

Then at 6.20pm on July 9, he was driving on Dundee's Pitkerro Road when he ploughed into the boy who was crossing the road with friends.

Fiscal depute Eilidh Robertson said: "He 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 and he 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 he was 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 would give his plea in mitigation at a later sentencing date.

Sheriff Tom Hughes deferred sentence until next month for social work background reports. Kozlowski was remanded in custody.
