Noah Banjo Turnbill, 19, pleaded guilty to assaulting a bystander after crashing his car in October

A teenager has pleaded guilty to assaulting a complete stranger, calling them a “snitch” and a “dog”, after they called authorities to a crime scene.

A southern suburbs teenager pleaded guilty to assaulting a member of the public, calling him a “snitch” and a “dog” after he called authorities.

Noah Banjo Turnbill, 19, appeared in the Christies Beach Magistrate Court, pleading guilty to three charges including due care, failing to stop and give particulars to persons at crash scene and assault at Aldinga.

A police prosecutor told the court the teenager failed to negotiate a bend along Harvey Ave, crashing his Holden sedan into a fence.

“Initially it was reported by a member of the public who had been sitting at home when they heard a loud bang,” she said.

“They saw a vehicle in the fence yet no driver and proceeded to call the police.”

The court heard while the victim was on the phone to police, Turnbill returned to the vehicle and was seen offering members of the public money to not call police.

“He was also being aggressive, when the victim approached him he was called a dog and snitch,” the prosecutor said.

“He (Turnbill) has then punched the victim in the face, resulting in a cut lip and a sore jaw.”

Turnbill’s lawyer Peter Hill said his client was essentially “off his face” on drugs at the time of the incident.

“At the time of this incident he was heavily intoxicated on drugs and he described to me very frankly, he was ‘off his face,” Mr Hill said.

“He was confronted by a member of the public and he struck that member once, not a sustained attempt.”

Magistrate Teresa Anderson told Turnbill to address his issues and to get his life on track.

Turnbill was sentenced to a one month and 24 day term of imprisonment, suspended into a good behaviour bond for 12 months.

He was also disqualified from driving for 28 days and fined $300.
