Commodity thieves generally don’t worry about leaving some valuable pieces behind. The Louvre robbers tried to steal a crown that had belonged to Empress Eugénie, featuring eight gold eagles, 1,354 diamonds, 1,136 rose-cut diamonds and 56 emeralds. But they abandoned it in their haste to leave.

A new video has emerged showing what could be the Louvre thieves in action as they carried out Sunday’s daylight robbery at Paris’s world-famous museum. The footage, obtained by French broadcaster BFMTV, purportedly shows what has been called one of the most brazen art thefts in recent memory.

Thieves broke into the museum's Galerie d'Apollon and made off with "priceless" jewelry, French interior minister Laurent Nuñez said.
