(Portland, OR)  --  Police are looking for a group of burglars who broke into a chocolate shop in northeast Portland.  Police say the thieves broke into Woodblock Chocolate shop late last week and stole keys and a credit card along with a handful of Peruvian chocolates and two bucks from the tip jar.  Shop co-founder Charley Wheelock tells KATU the thieves were overly nice and even closed the door behind them, but they did steal a sense of safety from staff there.  Anyone with information is urged to contact police.
