The Department of State Services (DSS) has issued a warning to those it said are calling for a change in power under the banner of the Nigeria Continuity and Progress (NCP).
The warning is coming few days after the Nigerian Army distanced itself from a coup plot.
The DSS in a statement on Friday said: “It is evident that the misguided group and its cohorts have also planned to instigate widespread violence against the government in order to actualize their infamous agenda of forceful change of regime.
“The DSS not only supports the consolidation of democracy in Nigeria, but will leave no stone unturned in rooting out persons or groups desirous of truncating the process or undermining the country’s peace and corporate existence.
“The service will, therefore, not condone any form of extra-judicial activities or methods designed or adopted by persons or groups to subvert constituted authorities.
“Instructively, defaulting persons will surely be brought to book".
