PARIS (Reuters) -The audacious daytime robbery of historical jewels worth $102 million from the Paris Louvre museum last month was executed by petty criminals, rather than professionals from the world of organised crime, the Paris prosecutor said on Sunday.

On a Sunday morning two weeks ago, two men parked a movers' lift outside the Louvre, rode up to the second storey, smashed a window, cracked open display cases with angle grinders, and then fled on the back of scooters driven by two accomplices in a heist lasting less than seven minutes.
