A young woman has been left distraught after Victoria Police told her she would get no compensation for her written-off car after she was unwittingly used in a police roadblock to stop a fleeing driver.

In an effort to stop a man fleeing at high speed along the Tullamarine Freeway on Sunday, police set up a roadblock, stopping the woman's car. The fleeing driver, in a Hyundai van allegedly filled with stolen goods, then ploughed into the back of her car.

He was arrested by police on the scene.

The woman's car is a writeoff. Victoria Police says its insurer won't pay because a police vehicle was not involved in the crash.
