The Department of State Security (DSS) said it has uncovered a plot by some unnamed persons to stage violent protests across the country.
It said the plotters include some politicians who were mobilising student and tribal leaders for the planned action.
A statement issued by the spokesman of DSS, Peter Afunanya, said it identified the ring leaders of the plot as well as sustained monitoring around them in order to deter them from plunging the country into anarchy.
