A MAN threatened a Carrum Downs woman with a knife before forcing her out of her car in the driveway of her Lats Av property and stealing it, 4.30pm, Saturday 16 September.
The woman, 48, told police that she had just sat down when the man knocked on her side window and produced the 15cm knife.
She opened the door and the man pulled her out and they had a brief struggle after which the man drove off in her grey 2012 Hyundai Ascent.
Only two and a half hours later the man was chased by police at Bairnsdale after allegedly forcing other cars off the road.
The speed at which he was driving and his erratic behaviour caused police to end the pursuit.
He is described as Caucasian, 30s, 162cm, stocky build, shaved head, acne-scarred face and tattoos on his right arm.
