British banknote printing company De La Rue has approached the Serious Fraud Office (SFO) following an investigation that revealed irregularities in note printing.
The largest banknote printer in the world partners with governments and central banks to makes paper currency for 150 countries. It said in a statement on Tuesday that it had contacted "relevant law-enforcement agencies" with its findings that some employees had "deliberately falsified" tests on paper used to make bank notes.
"It has now been established that some of the company's employees have deliberately falsified certain paper specification test certificates for a limited number of customers," said De La Rue.
The problem has been traced back to a contract of supply paper. The company's investigation revealed that certificates of quality for some its paper stock had been forged.
An SFO spokesperson confirmed that De La Rue had passed on the information to the agency. "It is premature to say that a formal investigation has started. But we are monitoring the situation," he added.
Reports suggest that the paper in question was meant for the Reserve Bank of India.
