The suspects approach the victims on foot, grab jewelry or bags using force or fear and flee to a waiting vehicle, Iacono said.

Police urge citizens to be aware of their surroundings and vigilant of suspicious people, especially as the holiday season approaches, Iacono said.

Police recommend walking in groups and keeping valuables out of plain sight to avoid being victimized.
