On 7/18/18, at approximately 8:45 p.m., three Hispanic males and one Hispanic female entered a retail jewelry store. The thieves distracted sales associates by having them assist the female by looking at clothing in another area of the store. At that point, the male subjects obtained keys which were inside a cabinet. The males opened a diamond ring case and stole 21 diamond rings. The males ages ranged from 20’s to 30’s. The males had short hair and no facial hair. If you have any information regarding these subjects, please call the Jewelers Security Alliance at 212-687-0328.
