Karen McFadden and her husband Simon - the brother of Nick McFadden, an officer who sold seized drugs - lived the "high life" on the proceeds of the stolen drugs.
Leeds Crown Court heard the couple spent £160,000 in a matter of months. Karen McFadden, 41, spent thousands in Harvey Nichols and Vivienne Westwood.
She bought bikinis at £160 each, and a private number plate for her MX5.
She explained her fortune away by claiming they were casino winnings. The prosecution said Karen McFadden, who admits money laundering, spent the money knowing it was the proceeds of her husband's criminal activity but without knowing the finer detail of how he had come about the cash.
