Woman carjacked at gunpoint after leaving gym in Adelaide

Police are hunting a second suspect after a woman was carjacked at gunpoint as she left a gym in Adelaide.

The 22-year-old had driven herself to the gym and was ambushed as she returned to her car on Stanbel Road at Salisbury Plain just after 10.30pm last night.

It's alleged when she reached her car, two men pulled a gun on her, stealing her Holden Barina and abducting her.

They allegedly dumped her in a nearby street before setting the car alight in Elizabeth Park.

Police later charged a 33-year-old man at a house in Elizabeth Grove, seizing a number of firearms.

The second man is yet to be found.
