Police in the UK are on the hunt stylish thieves who lifted Victoria Beckham’s $630,000 collection of new dresses in a staged robbery.

The former Spice Girl is reportedly shocked over the robbery of up to 75 dresses from her exclusive fashion line. The frocks due to go on sale at tony New York department store Neiman Marcus, were stolen as they were being driven to London’s Heathrow Airport, The Courier-Mail reports.

Police believe the van may have been followed after picking up the dresses.After stopping to make a delivery, the van’s driver returned to find its padlocks broken and two men emerging from the vehicle carrying boxes.

The driver told police he was knocked over, threatened with a knife, and left bruised and shaken after the men pushed past him to make their escape.

“This operation was meticulously planned. The thieves must feel they can make a fortune selling the collection on the black market,” a source said. “Victoria was informed straight away about the incident and was shocked and deeply saddened, although her first priority was the well-being of the driver.”
