The Royal Newfoundland Constabulary says two stores in St. John`s are out thousands of dollars after a man used a worthless prepaid credit card to buy jewelry. 

According to a release sent Friday, the RNC has had two complaints of fraud since Aug. 8. In both cases, a man saying he was from out of province purchased items with a prepaid credit card.

Days later, the stores were told that the transaction was fraudulent.

In total, the RNC says the man made away with $20,000 of merchandise. They believe the incidents are related and that the man may try it again. They are advising businesses, especially jewelry stores, to keep an eye out.
