Police are looking for at least four people in a series of robberies in Manhattan and Queens.
The incidents came in late June and early July, all of them in the early morning hours concentrated in southern Manhattan and eastern Queens.
In most cases, one or more of the robbers shows a weapon and demands money and other items.
In a few cases they also demanded pin numbers for debit cards.
Police say one of the robbers used a credit card stolen in one of the Manhattan robberies.
All are believed to be in their early to mid-20's.
Police also say a white car has been seen at several of the incidents.
