Art crime detective Arthur Brand warns that museums worldwide are increasingly vulnerable to theft, but the targets are changing. Historically, paintings were the primary focus, but their unique nature made them difficult to discreetly sell. Over the past decade, criminals have shifted their attention to objects containing gold, silver, and gemstones due to their easily disassembled and marketable qualities. Brand explains that these materials can be melted down or dispersed, making them less traceable than a singular painting. This represents a growing trend of sophisticated criminal opportunism within the international art world. The detective’s observations highlight a significant evolution in art theft, posing a challenge to museum security globally, and indicating all museums have been, and will be, victims of theft.
