Police said the thieves cut power to the warehouse before breaking in and swiping 20 boxes of the pricey handbags.

A Dooney & Bourke bag retails for as much as $500.

“When you find them stealing a lot of one item it’s usually because they’re going to go out there and resell them at a thrift store, a pawn shop, a swap meet, anything like that,” Sgt. Robert Morris said.

The sergeant said thieves typically put their loot for sale on eBay or Craigslist.

The manager of the Dooney & Bourke distribution center said he thinks the suspects were a team of professional burglars.

Although power was cut, security cameras caught footage of the suspects. The center manager did not yet want to release the video.
