On the evening of 10/1/19, four subjects arrived at a jewelry store in a white vehicle of an unknown make and model. The subjects exited the vehicle and approached the front entrance. The subjects entered the foyer but were unable to enter the location due to the interior doors being locked. The subjects wore hoodies, masks, and gloves. At least one of the subjects was armed with a hammer. If you have any information regarding these subjects, please call the Jewelers’ Security Alliance at 212-687-0328.
