Man arrested over Victoria child abduction

Victorian police will seek the extradition of a man from NSW over the abduction and sexual assault of a young boy in Melbourne.

Victorian police contacted their NSW counterparts on Tuesday about a man they were searching for following a nine-year-old boy's abduction and assault last week.

Acting on the tip-off, police stopped a car on Tuesday night in Auburn, western Sydney, and arrested the 21-year-old driver.
