On 2/20/19, at approximately 8:50 p.m., two subjects entered a jewelry store and yelled for everyone to get down on the floor. The sales associate and guest in the store complied with the demands of the subjects. One of the subjects pulled out a hammer and proceeded to break two showcases while the other subject ordered associates to stay on the floor. One of the subjects grabbed several diamond rings and placed them into a backpack that he strapped in front of his body. The first subject was described as a 6’0” tall Black male. He was last seen wearing a black hoodie and red ski mask. The second subject is 5’11” and has a slender build. He was last seen wearing a maroon hoodie and backpack. If you have any information regarding these subjects, please call the Jewelers’ Security Alliance at 212-687-0328.
