Thieves raid the Villena Museum in the Spanish town of Villena and steal the Bronze Age Treasure of Villena, one of Europe’s best-known prehistoric gold collections. Multiple outlets describe the attack as extremely fast, with the theft taking only minutes early on Thursday.

The reports say the collection includes 50-plus mainly gold objects, commonly described as a 50-piece or 66-piece group, with gold estimated at about €1.7 million. The Guardian and Free Press Journal report that most, if not nearly all, of the treasure is taken, while Al Jazeera says it is not yet known how many items are stolen. The Local and IOL also characterize the raid as “super-fast.”

Authorities and local officials cited by outlets say the museum’s alarm goes off around 5:20am and the thieves leave by shortly after, and that investigators are examining how the thieves entered. The heist is presented by outlets as part of a broader pattern of high-profile museum thefts in Europe, with police and researchers warning of increasingly violent or professional approaches.
