Police say a woman was arrested at the Freeport Marshall's after allegedly using fake traveler's checks.
Police say Shirlena Cooper, of Brooklyn, was trying to use the fake checks yesterday afternoon.
Detectives say that when a worker questioned her about the American Express Travelers Cheques, Cooper grabbed them and tried to leave.
Police say an off-duty Hempstead police officer who had been shopping in Marshall's grabbed Cooper and held her until police arrived.
