Vic woman on the run with children

A Victorian woman is wanted for questioning over child stealing.

Police believe Chantelle Spencer is on the run with her four children - two boys aged 14 and nine and two girls aged 13 and seven.

The 32-year-old was last seen in Shepparton on Tuesday and may be heading to Mildura, or Broken Hill in NSW, in an old Ford Fairlane sedan.

Police on Thursday released images of the Shepparton woman and her car. They are asking anyone who sees her to call Triple 0.
