Car stolen at gunpoint in Melbourne

A woman has been threatened with a shotgun as thieves made off with her car outside a Melbourne supermarket.

The woman had returned to her car after shopping at a Pascoe Vale supermarket at 1.40pm on Saturday when she was approached by a man armed with a shotgun who demanded she hand over the keys to her 2009 SSV Holden Commodore, police say.

Another man driving a gold-coloured Commodore is believed to be linked to the incident.
