Three boys have been charged after allegedly storming through junior soccer matches at an oval in Armadale and stealing a spectator's handbag.
Kids as young as seven ran off the field at Morgan Park yesterday morning, as the trio tore around on a red motorbike.
Witnesses said the youths brandished kitchen knives, and stole a woman's handbag during the rampage.
A 12 year old and two others, aged 13, were later arrested at homes in Armadale and Brookdale and charged with various offences including aggravated armed robbery, stealing and reckless driving.
They're expected to face the Perth Children's Court today.
