Thieves raided a museum in eastern France in broad daylight Friday, making off with a gold necklace dating back 2,500 years, prosecutors said.
Dijon prosecutor Olivier Caracotch said the thieves smashed a display glass sheltering the celtic-era jewellery at the Chatillon-sur-Seine museum in Burgundy.
Local mayor Jeremie Brigand said there had already been two recent attempted burglaries at the museum before Friday morning's theft.
Although the museum had tightened its security after the previous two attempted thefts, the thieves were organised, fast and determined enough to carry off the theft, he added.
"The individuals acted in broad daylight to steal the necklace despite the presence of the public, staff and a security detail."
