The boy asked for 15 euros worth of candy, prompting the suspicious kiosk owner to ask him whether he had enough money for such a generous provision of sweets. The boy then pulled out a huge wad of notes totalling 1,680 euros.
Police were called and the parents, who had saved up the cash for house repairs, came to pick up their sweet-toothed son.
The boy said he had stolen the money from his parents' drawer, police in the western town of Viersen told AFP.
