He is due to appear in court in Mackay on Monday.
FOUR juveniles, including two boys aged 10 and 13, have assisted police with their inquiries into a massive fire that gutted a shopping complex in Mackay today.
Police say the 10 and 13-year-old boys are still assisting them with "ongoing investigations".
No one was injured.
Much of North Mackay was in lockdown when an emergency situation was declared, causing major traffic chaos with local streets in gridlock.
At 4pm, police lifted the emergency situation and reopened all roads, but a public safety order is still in place because of police concerns about toxic smoke from burning chemicals in some of the shops.
A police spokeswoman confirmed four juveniles were in police custody in relation to the incident.
One is understood to be a 15-year-old girl.
The fire, first reported to police at around 11.45am, saw Toys'R'Us, Autobarn and Clark Rubber totally engulfed by flames and a huge smoke plume cover the area.
Up to ten fire crews were called to Greenfields Boulevard to fight the blaze, which continued burning for almost five hours after the first Triple-Zero call was made.
Busy Saturday trading at the Toys R Us Mackay saw a mass evacuation from the building, and at 1.20pm, the roof of the Toys R Us was reported to be caving in.
Motorists are advised to avoid the area.
