(YouTube) (Newser) – French media are praising a Muslim worker who apparently saved several people during the siege of a kosher grocery store in Paris yesterday, the Huffington Post reports. According to RTL and Le Parisien, Lassana Bathily ushered several customers into a freezer when terrorists seized the Hyper Cacher store. "I went down to the freezer, I opened the door, there were several people who went in with me," says the 24-year-old from Mali in west Africa, the Telegraph reports. "I turned off the light and the freezer." He told them to keep calm and went out through a freight elevator. Police apparently took him for a terrorist, keeping him cuffed for about 90 minutes, but he then helped police by describing the layout of the store.
