12yo charged over crime spree

Police in Perth have charged a 12-year-old boy they claim was involved in a three-day crime spree.

The boy has been charged with several serious offences, including stealing a motor vehicle and aggravated armed robbery.

It is alleged he and three accomplices aged between 17 and 25 stole a car on Friday night before using it to steal handbags from three women around the metropolitan area.

Police say two of the women were threatened with a knife.

The stolen vehicle was involved in a high-speed pursuit last night, reaching speeds of up to 160 kilometres an hour before it was stopped by police with a stinger device in Willeton.

The pursuit began on the Kwinana Freeway just after midnight, when police spotted a stolen vehicle.

It continued for about half an hour through Perth's southern suburbs, as well as the domestic and international airports.

The driver lost control of the vehicle on Leach Highway in Riverton after he tried to avoid the stinger device.

The driver escaped on foot but was arrested a short time later.

They boy's three accomplices - two females and one male - also face several charges, including stealing a motor vehicle and armed robbery.
