This is contained in a statement issued by Dr Peter Afunanya, the Public Relations Officer of the DSS, on Monday in Abuja.
He said the syndicates were intercepted by operatives of the service during an operation.
“Investigation has also shown that some Commercial Bank officials were aiding the economic malfeasance.
“Consequently, the Service warns the currency racketeers to desist from this ignoble act.
“Appropriate regulatory authorities are, in this same vein, urged to step up monitoring and supervisory activities to expeditiously address the emerging trends,” he said.
He said the DSS has ordered its commands and formations to further ensure that all persons and groups engaged in the illegal sale of the notes were identified.
The DSS spokesman, therefore, urged anyone with useful information relating to the sales of the new currency to pass the same to relevant authorities.
