CCTV footage released by police shows the horrific moment Lucas Gary Narkle, 19 grabbed his girlfriend off a seat before dragging her to the edge of a platform in the nortnern suburbs of Adeilaide, towards a moving train.

The young girl, who was 14 years old at the time of the incident last October, is seen losing grip of the chair and resisting, before they both fall to ground.

After his failed attempt, he tries again, this time sitting next to her, pinning her down on another seat.

She is seen clinging onto the handle of the bench with one arm.

As soon as another train approaches the platform, Narkle pulls her off the seat and again drags her quickly to the edge of the platform.

In one final attempt to push her in front of the nose of the train, the young girl continues to resist and they both fall to the ground.

The confronting footage shows that she was less than a metre from being thrown in front of the moving train.

Narkle faced the District Court on Wednesday after earlier pleading guilty to endangering the girl’s life in October 2017.

The court heard his girlfriend, could be seen “holding on for dear life” as she was dragged along the station platform by Narkle.

“She wasn’t to know that he was going to stop,” a prosecutor said of the offending, which was captured on CCTV at a train station in Adelaide’s north.

“There’s no telling what harm that fear may cause in the future.”

Narkle — who was initially charged with attempted murder — was armed with a baseball bat but both sides agreed it was not used.

He was taken into custody following the incident and spent more than three months in prison until he was granted bail by the Supreme Court in February.

Narkle faced the South Australian District Court this afternoon but his sentencing had been delayed following a last-minute change of heart by his young victim.

AAP reported that a prosecutor told the court the girl – who had previously refused to co-operate with the investigation – had decided to tender a victim impact statement.

Judge Simon Stretton agreed to a request to delay sentencing, and Narkle’s bail was continued until a hearing next week.

The judge said he was unlikely to impose a jail sentence on Narkle.

“I have to bear in mind that his actual actions here are brief, irresponsible and didn’t cause any physical harm at all,” he said.

“I think nothing is going to be served by imposing a further term of actual imprisonment but I am strongly inclined towards an extended community service work.”

Narkle arrived more than 30 minutes late for the hearing yesteday, blaming public transport issues for the delay.

“Shout out to my boys in Yatala (Labour Prison),” was his only comment to reporters outside court.
