The Central Bureau of Investigation examined former Department of Economic Affairs Secretary Arvind Mayaram on Tuesday regarding alleged corruption in an exclusive color shift security thread contract for Indian currency notes. The CBI registered an FIR in January 2023 involving Mayaram, Finance Ministry officials, the RBI, and De La Rue International Limited. The investigation alleges the company lacked patent verification when selected in 2004, and the contract was extended multiple times without proper termination clauses until December 2012.
