A woman in the US had her car stolen on the side of road by the men she had stopped to help.

Jennifer Jones was driving home in Hawaii on Sunday, when she saw a SUV swerve and crash into a barrier. on the freeway.

Leaving her keys in her car, she stopped to help the two men and a blood-covered woman in the SUV, as smoke poured from their vehicle.

“There was a woman hanging half out of the passenger side and she looked pretty bad. There was blood all over her,” Ms Jones told the US TV station KHON2.

Ms Jones, who is trained in First Aid and CPR, tended to the woman, and was confused when the driver asked her if she needed a taxi.

She described how the man: “just kind of backed away looking at me, then all of a sudden my brake lights went on and burned rubber and it screeched off.”

“It took a minute to register that this man just stole my car,” she said.

“Who's going to come steal your car while you're rendering first aid? It's just unfathomable that someone would do it,” she added.

The bloodied-victim explained to Ms Jones that she had been hitchhiking, and the car had crashed during a struggle between her and the two men when they allegedly held a knife to her.

It later emerged that the woman was the girlfriend of the driver, and her story was untrue.

Ms Jones said: ”The police later informed me that indeed that car was stolen and those three people had just taken it off of a dealership lot.“

Authorities were able to locate her Mazda convertible nearby, by using an app to track her phone that was inside.

The car was found with its interiors wrecked, but most of Ms Jones' belongings, as well as some of thief'’s clothes, were inside.

Hawaii News Now reported that the police arrested a 22-year-old man at the scene but are still looking for the driver.

The woman was treated at a hospital.

Undeterred by the incident, Ms Jones said: "Their bad actions aren't going to change my good actions.

"I would still stop today if I saw a car. You know, it’s, it's the right thing to do. It's Hawaii, we should be watching out for each other.”
