A hit-and-run driver who left a teenage girl with life-threatening injuries has been jailed for two years.

Naomi Ahmed suffered multiple fractures to her legs, pelvis, arms, hands and ribs and was in intensive care for days after the incident on November 14, 2015.

John O'Neil, 32, denied driving dangerously and leaving Ms Ahmed, who was 19 at the time, seriously injured.

A jury at Dundee Sheriff Court on Wednesday found him guilty of causing serious injury by dangerous driving.

They were then told O'Neil had previously been jailed for taking a car without consent and driving without a licence or insurance.

A three-day trial earlier heard O'Neil was a provisional licence holder, had only taken five driving lessons before the crash and failed his driving theory test.

He claimed he was travelling at between 25mph and 30mph when he crashed into Ms Ahmed but one witness told the court he was driving "like a boy racer" and another said he was going "very, very fast".

O'Neil stopped immediately after the crash and told a witness he had not seen Ms Ahmed.

He then got back into the car and sped off before abandoning the vehicle in the next street.

Fiscal depute Vicki Bell told the jury that when Ms Ahmed was found on Byron Street in Dundee she was "unconscious and only responding to pain".

"She was covered in blood on the face and blood was on the road," the fiscal added.

The teenager had a chest injury, broken bones and ribs, a significant head injury, a suspected abdomen injury and a broken leg.

Ms Bell said: "She was sedated and taken to Ninewells Hospital where a CT scan revealed bleeding on the brain.

"A pressure monitor was inserted and she underwent an operation to repair her leg. She also underwent operations to repair her left hand.

"She still experiences pain and swelling in her leg and there is permanent scarring."

Sheriff Alastair Brown jailed O'Neil, of Rosebank Street, Dundee, for two years and banned him from driving for five.

The sheriff told him: "You drove too fast. You failed to stop in time and failed to avoid Naomi Ahmed - probably because you were driving far too fast.

"That's a consequence of your incompetence as a driver and your selfishness in the way in which you drove."
