Thieves with gun steal Vic woman's car

A woman was held up with a shotgun in a supermarket carpark and two carjackers stole her car while another was waiting in a getaway vehicle.

Carjackers threatened a woman with a shotgun at a Melbourne carpark before stealing her car.

The 50-year-old woman was shopping at a supermarket in Pascoe Vale in July, and when she returned to her car she was held up by two men, one brandishing a shotgun, police said on Wednesday.

Police have released photo-fit images of three men, two who took her car and another who was waiting in separate getaway vehicle.
