Accused western Sydney arsonists arrested

Five people face criminal charges over a spate of arson attacks in western Sydney over the last three years, including some that involved Molotov cocktails.

A NSW Police strike force has been investigating more than a dozen fires that either damaged or destroyed cars, trucks and houses between August 2014 and June this year.

On Tuesday police revealed four men and one woman, aged between 20 and 53, had been arrested and charged with various arson-related offences.
