A Taiwanese woman on a working holiday was the victim of an attempted kidnapping when she was forced into a car boot in Sydney's inner west, police say.
The 27-year-old was walking near Burwood train station shortly after 10am on June 4 when she was grabbed by a man and forced into the back of a car, Inspector Michael Boutouridis told reporters on Friday.
When the woman fought back, her attacker punched her in the face.
"Thankfully, a gentleman, a good Samaritan in fact, was driving past and he stopped," Insp Boutouridis said.
"He stopped and yelled out and we believe that was enough to distract the offender and it gave the woman an opportunity to get out of the boot and run off."
The victim had been in Australia for about two months and was thought to be starting a new job the day she was attacked.
After the woman ran off, her attacker - believed to be aged in his 20s, between 180 and 190-centimetres tall, of muscular build and Caucasian - drove away and police are searching for the car.
They know who its registered owner is but do not necessarily think that person is responsible for the attack.
The car is bright blue Holden Captiva SUV with Queensland registration 362 RUL.
