Police say the suspects smashed the store’s glass cases and stole jewellery.

They say officers gave chase and arrested one suspect, who was charged with robbery disguise with intent and assault with intent to resist arrest.

Police allege the same suspects left a package at the Markham GO train station as a diversion tactic to draw police resources away from the heist.
