On 1/17/19, at approximately 7:14 p.m., two subjects entered a jewelry store and immediately yelled: “get down!” One of the subjects then said, “don’t push any button!” Two additional males then entered the store. The four subjects approached two diamond showcases and began smashing glass cases with a small sledgehammer. Once the glass was penetrated, the subjects removed loose diamonds as well as earrings and pendants. If you have any information regarding these subjects, please call the Jewelers’ Security Alliance at 212-687-0328.
