UPDATE: Police have released an image of a man who may be able to assist their investigation into a brazen act of carjacking in Footscray on Thursday.
The man, armed with an edged weapon, climbed into the passenger seat of the BMW outside Footscray Market just after 1pm and demanded 31-year-old Point Cook woman drive to an ATM, Victoria Police said.
The car ended up in Union Road, Ascot Vale, where the woman was forced to get out of the car and withdraw cash at an ATM.
She handed over the cash to the man, who then fled.
