"My take would be someone who learnt [from the Pink Panthers] and made it better," Selby said, although he concedes that "anyone who is smart enough to put on four hours of makeup is clever enough to fake an accent."
The Graff Diamond stores have been hit before by thieves, including the Pink Panthers. In 2003 suspected Panthers made off with 47 pieces of jewelry valued at $23 million. One item was a $1 million blue diamond was later retrieved during the search of a gang member's London apartment. It had been hidden in a pot of face cream.
And in 2007 another London branch of Graff Diamonds was robbed of $17 million worth of jewelry by two men in a chauffeur driven Bentley Continental Flying Spur.
Pape said it would seem the jewelry chain would want to increase its security.
The store "should have more security, but more security will keep their customers away," Pape said, and "make their customers feel uncomfortable." He said it is unlikely that, given the affluent nature of the stores' clientele, Graff Diamonds would do such things as frisking their customers.
