When a dapper young bank teller in Ottawa made off with hundreds of thousands of Canadian dollars and slipped across the border in 1958, he instigated an international manhunt.

A wanted poster circulated by the authorities showed a young man, grinning in a white tuxedo and black bow tie. The description included his height, weight and personality: “neat dresser, nightclub habitué, a champagne drinker, enjoys female companionship.”

Sixty years later, the bank teller, Boyne Lester Johnston, known by some as the “champagne kid,” returned to the scene of the crime. Mr. Johnston is now in his 80s, and the old bank is now a hip downtown restaurant, Riviera.

During a lunch at Riviera, on Aug. 10, Mr. Johnston drank Champagne cocktails and visited the wine cellar, which was formerly the bank vault, said Alex McMahon, the restaurant’s wine director.
