COPENHAGEN, Denmark (AP) — At least two thieves have stolen items from an art gallery in Stockholm, police said, with Swedish media reporting that they include 10 to 12 table-size bronze sculptures by Spanish artist Salvador Dali.

Police said “at least two thieves” entered the Couleur gallery in central Stockholm early Thursday morning by smashing the entrance window. Forensic experts were searching the gallery for clues and no suspects have been arrested.
