Vienna Museum Had Security Plan When $4M Diamond Necklace Was Hammer-Stolen

Two men smashed a glass case at Vienna's MAK museum with a hammer and stole a 673-stone diamond necklace made for an Egyptian queen, valued near $4 million. Director Lilli Hollein confirmed a security plan existed with partner Van Cleef & Arpels. Staff followed procedures; none were injured. The theft's ease raises questions about physical security at museums holding irreplaceable assets.
