The Department of State Services (DSS) says it has identified persons and groups planning to stage campaigns of calumny against it and the government over the suspension and investigation of the Central Bank governor, Godwin Emefiele.
Spokesperson of the service, Dr Peter Afunanya, made the revelation in a statement on Saturday.
In the plot, the groups intend to gather at different points in Abuja and Lagos with placards depicting the DSS and the Federal Government in bad light as well as calling for the immediate release of Emefiele.
The service said the perpetrators, which it said had been put under surveillance, had lined up activities aimed at painting the service and government in bad light as a result of the suspension of Emefiele.
The Service therefore warns those behind this plot to desist forthwith.
Meanwhile the service says it has granted the family of Emefiele, medical officials and appropriate persons access to him, right from the day he was taken in and obtained a court order to do so.
The Service implements Standards Operating Procedures on Suspect Handling and Investigation professionally.
