"We are not seeking anyone else in connection to this incident."
Three teens - two aged 18 and a 16-year-old - had previously been apprehended by police and also face youth court.
Panicked shoppers initially thought shots had been fired about 3.25pm in the busy mall.
It was later identified as the sound of glass breaking as thieves allegedly tried to smash their way through a cabinet to items held at the Silvermoon jewellers, but were unsuccessful.
They did, however, manage to get away with "a quantity" of jewellery from the nearby Michael Hill Jewellers store, police said.
After fleeing the scene, the group - said to be wearing black masks - allegedly made off in a stolen vehicle, which was then abandoned at the Baldwin Ave train station before they boarded a train to Kingsland.
The group managed to get on another train bound for Ranui, where three were caught by police.
