В северной Франции thieves stole jewelry worth up to $1.2 million, police announced today, about a month after the famous Louvre heist. According to French media reports, the robbers broke into a jewelry store in the center of the city of Roubaix near Lille on Wednesday. They held the jeweler and his wife for a short time before fleeing with the precious jewels. Police estimated the value of the stolen jewelry at between $580,000 and $1.2 million and announced they had launched an investigation into the crime. In a separate incident on Wednesday, several people blew up a safe at the main post office in Roubaix and fled with a bag inside. It was later revealed that the bag contained empty bags, while six people were arrested in the evening. These two thefts come after a gang stormed the Louvre Museum in Paris in broad daylight last month and stole jewelry worth about $102 million.
