A man recently visited the store of Ambrose Kent & Sons. Toronto, Ont., and asked to look at some rings. He made a close inspection of the articles without purchasing, and W. L. Wilkinson, who was showing the rings, noticed that two of them, worth about $20, had disappeared. He asked the pretended customer to replace them, but the latter protested that he had not taken them. A detective was sent for but before he arrived the thief restored one of the rings. He was given in charge and turned out to be John Oliver, an expert thief, well known in Hamilton. Ont., and formerly of New York State. He had tried the same trick at Mr. Forsyth’s store, Queen St., W., shortly before his arrest, but unsuccessfully. Numerous others, however, have been defrauded. Oliver was subsequently brought up at the Police Court and committed for trial.
