GARDEN CITY, N.Y. — Nassau County’s top police official was stopped on suspicion of using counterfeit cash while Christmas shopping last month, but the bills were later determined to be real.

Newsday ( ) reports that Acting Nassau Police Commissioner Thomas Krumpter was never charged with a crime. Krumpter declined to speak to the newspaper, which obtained a copy of the case report.

The report says Krumpter was shopping at the Roosevelt Field mall in Garden City on Dec. 23 when he made a purchase using four $100 bills. Sales associates checked the bills and suspected they were potentially counterfeit.

Police responded to the scene and rechecked the bills and authenticated them. The cash was still taken as evidence. The Secret Service, which investigates financial crimes, later confirmed the bills to be genuine.
