A suitcase containing 25 bags of white powder understandably caught the attention of police at London's Gatwick Airport. Tests on the powder and questioning began, the Guardian reports. In the end, police said, "It was determined these bags of powder were cake ingredients for a vegan bakery." The mule turned out to be an employee of a vegan pizzeria, who was given the suitcase and ingredients back. Transport police tweeted Wednesday about their "huge drugs bust," advising to "please label your foods and bring samples of cakes next time you visit." The Brighton pizzeria employee suggested cake as a peace offering when the law enforcement officials are in town. (More Gatwick stories.)
