Police said the alleged kidnappers, who had firearms, severely assaulted both the woman and her eight-year-old son with a baseball bat before forcing the woman into an SUV.

Officers were later called to the suburb of Beverly Hills just before 11.30pm on Thursday following reports of a car fire. Crews extinguished the blaze, but the car was destroyed and a body was located inside.

Superintendent Rodney Hart said they had made contact with the father of the boys, and the woman’s husband, who had been intestate on business. Source: AAP
