The woman was driving late on Monday night in Nossebro, in western Sweden, when she was pulled over by a car with flashing blue lights.
Certain that it was a police vehicle, the woman pulled over, but her suspicions were aroused when the self proclaimed “policeman” demanded the keys to her car, wrote the Göteborgs-Posten newspaper (GP).
The woman then asked to see the man’s identification, which allegedly irritated him, prompting him to make a grab for the car keys.
However, the car’s central locking system kicked in and the woman put her foot to the floor, fleeing the scene with the would-be car thief still halfway through the window.
The man kept hold of the car door and was dragged 100 metres by the woman, meanwhile managing to rip her clothes and steal a gold necklace from around her neck.
The woman managed to escape soon after, reporting the matter to the local police, who have launched an investigation, and are currently on the lookout for a dark and new Volvo, which is believed to have contained two passengers.
The woman was not injured in the incident, though was reportedly shocked.
