When a Bankstown father went to help a young woman in need, he never envisaged his act of kindness would turn his life into a nightmare.

But that's what happened to 36-year-old Kenan Basic.

He had been accused of indecently assaulting and stalking a 19-year-old woman he had helped after her car broke down at a BP service station in Sydney's west in late 2018.

On Monday, the charges against Basic were thrown out in Bankstown Local Court after the woman admitted to making it all up.

Caitlyn Gray pulled into the BP in November after she smashed her car, and Basic offered to help with the damage.

He spent almost two hours helping Gray get her car back on the road.

They appear happy and even hug before Gray gets back in her car and leaves.

Gray told police Basic had allegedly propositioned her for sex in return for his help before he pursued her in the car and later indecently assaulted her at a different location.

At the time, police described Basic's alleged behaviour as "predatory".

7NEWS has been told Gray has since admitted, in a recent police interview, to making everything up.

Her motive, however, remains unclear.

She’s been charged with contempt of court, fabricating evidence and lying to police.

'Mere luck'

Outside court, Basic's lawyer Mona Elbaba says all charges against her client were subsequently dismissed and withdrawn.

"My client and his family are extremely happy with the outcome," Elbaba said.

"He has always maintained his innocence, he's always said he's not guilty to the charges and has vigorously denied the allegations."

Elbaba says the truth came out after they pressed the police to investigate the matter further.

"I understand that there was some CCTV footage which contradicted her version, and the police obtained that footage by mere luck after we asked the police to investigate the matter further, and they did," Elbaba told 7NEWS.

"It's an extraordinary outcome for my client. Justice has been served and we are very happy with the outcome."

The relief on Basic's face was evident after he walked from court a free man.

"Finally this is over, so I am very happy," Basic said.

He said the past few months for him have been "terrible" especially when he knew he was innocent.

7NEWS has also been told Basic, who spent two weeks in jail, will pursue costs and compensation and will be back in court in July.

Basic also admitted he probably won't stop to help another woman again, and that the matter had "destroyed" his marriage.

Gray is due to face court next week.
