LIMA, Peru (AP) -- Peruvian banks have stopped accepting a particular series of $100 bills until U.S. Treasury Department officials can clear up an intelligence report warning of a virtually undetectable counterfeit, the head of Peru's banking association said Tuesday.
"We are in communication with the U.S. Treasury service for them to send us a specialist and indicate the characteristics of the bills that have been falsified," Enrique Arroyo, general manager of the Banking Association of Peru, told Radioprogramas radio.
He said U.S. officials had passed on an intelligence report about counterfeit hundreds carrying a 2001 series date and a CB-B2 serial code "that they themselves have not seen."
The U.S. Embassy did not immediately comment.
Supermarkets, department stores and money changers had also stopped accepting any bills carrying the suspect designations amid local media reports that a flood of false bills, produced in Pakistan, might have been distributed.
The U.S. dollar is accepted as a secondary legal tender in Peru, alongside the official currency, the Nuevo Sol.
Arroyo said the U.S. intelligence report, delivered over the weekend, indicated that the counterfeit bills are believed to be "almost perfect."
"We are waiting for them to let us know what characteristics define the real from the false (bills)," he said.
