“Police arrived at about 4.30pm and witnessed the trio walking out with another trolley load of items.”
Cook said two siblings were arrested attempting to leave the area on foot.
“A third person, a son of one of the others arrested, was taken into custody after being stopped a short distance away with a carload of groceries,” Cook said.
“Thanks to the community who quickly contacted 111, we were able to bring this matter to a swift conclusion.
“I would like to acknowledge everyone’s vigilance in reporting this offending to us, so we could respond.”
Police estimated the six trolleys worth of groceries were valued at more than $16,000.
