A Louvre security guard has described how he found a £10m royal crown on the floor outside the museum, after four thieves wielding power tools broke into the building in broad daylight.
Frédéric Serrier headed directly to the exterior of the Apollo Gallery just after the robbery took place, when he stumbled upon the 170-year-old crown once worn by French Empress Eugénie, on Sunday morning (19 October).
