SHEEPSHEAD BAY - Sheepshead Bay merchants say they are growing fearful of increased crime and reconsidering staying in the neighborhood. The latest incident, caught on surveillance tape, shows nearly a dozen men robbing Bionic Bagels on Nostrand Avenue. Store owner Mike Urciulo says the business used to be open 24 hours a day, but now he takes orders through a small window at night. A statistics report from the 61st Precinct indicates a rise in several different types of crimes since 2011.
