There was <a href="http://www.cnn.com/2015/04/09/europe/london-hatton-garden-heist/" target="_blank">no sign of forced entry on the outside of the building</a>, which houses numerous businesses. It appears the thieves disabled an elevator on the second floor of the building, then climbed down the elevator shaft into the basement where the vault is located, said Detective Chief Inspector Paul Johnson of the London Metropolitan Police's Flying Squad. The squad, which Brits often refer to as "The Sweeney," is the Met's branch dedicated to heists and armed robberies. "Sweeney Todd" is Cockney rhyming slang for Flying Squad. Get it? No? It's OK. Few non-Cockneys do.
