'Strong' Thieves Steal Museum's Viking Jewels Thieves 'used a lot of strength' to remove a first-floor window of Swedish museum By Matt Cantor, Newser User Posted Oct 22, 2013 11:15 AM CDT 9 comments Comments Lund University, home to the museum. (Shutterstock) (Newser) – A forensic unit has descended on a Swedish archaeological museum after thieves managed to steal an array of Viking artifacts—including precious jewelry—early today. "The thieves got in through a window on the first floor which they used a lot of strength to remove and which subsequently broke," the security chief tells the Local. An alarm went off at 2:45am, but by the time police arrived at the Lund University Historical Museum, the criminals had escaped. It's not yet clear exactly what was stolen from the the country's second-largest archaeological museum, and an inventory won't be conducted until police are finished investigating. It marks the museum's first theft since the 1950s. So how much were the stolen materials worth? "You can't discuss any value, as these items don't go on sale ... they are part of our cultural heritage," says the security honcho.
