POLICE allege three teenagers charged over the Aveley bushfire on the weekend put dry grass into a shopping trolley and set it alight.
The 15-year-old boy and two 14-year-old boys, all from Ellenbrook, were charged with breach of duty and will appear in the Midland Magistrates Court later this month.
Police claim the trio tipped the trolley over to try and extinguish the fire, but the flames ignited nearby scrub.
Strong winds spread the fire quickly and 25 hectares of land was burnt.
Yesterday, the Department of Fire and Emergency Services admitted its warning to residents was “not good enough”.
