The associate fled from the store and pulled an alarm on her way out. One of the subjects followed the associate and another fled on foot.  One of the subjects proceeded to enter a Lyft. The Lyft driver called police because he thought his passenger was acting suspiciously. Police responded and arrested the subject that was a Lyft passenger. The second subject remains at large.  If you have any information regarding this subject, please call the Jewelers’ Security Alliance at 212-687-0328.
