A man has been arrested in connection with the counterfeit bills dispensed at two ATMs in midtown Manhattan last week, authorities said.

Gene Carlo Pena, 26, was arrested at Kennedy Airport just after 4 p.m. after voluntarily returning to New York City from the Dominican Republic, the FBI said. He worked for a company that serviced the ATMs. 

He faces several charges, including embezzlement and other charges related to counterfeit currency. It's not clear if he has an attorney. 

The amatuerish fake bills were put in ATMs at two Chase branches -- one on 57th Street and one on Ninth Avevnue -- to replace cash that had been stolen. The banks were short a total of some $11,000.      
The counterfeit bills were blank on one side. Authorities believe they were meant to trick the ATM into believing it was carrying a full complement of cash.      

A bank official said that the machines were able to distinguish most of the fake bills from real ones.

The NYPD and Secret Service assisted in the investigation.
