Violinist Min-Jin Kym lost her £1.2m violin while in a London sandwich shop this week. Along with the Stradivarius in the case were bows valued at £62,000 and £5,000. The insurance company is offering a £15,000 reward. A worker at the sandwich shop pointed out that Kym and her friends were preoccupied with their computers and phones at the time and not paying attention to their bags.
