The Director-General, Department of State Security (DSS), Lawal Musa Daura, has reversed the promotion of the agency’s former spokeswoman, Ms Marilyn Oga and 44 others.
Sources said that the promotion, in the first instance, was considered to be politically motivated.
The acting DSS boss, in a memo, directed the demotion of other officers of the agency, who were promoted in March.
Ogar had become a controversial official of the DSS with her numerous statements that were deemed partisan.
Her promotion was, therefore, viewed as a reward for doing dirty political jobs for former President Goodluck Jonathan and members of the Peoples Democratic Party (PDP).
Promotions of officers in the DSS are usually done at the end of each year, but Ogar and 44 others were promoted last March.
The promotion was not made public until May.
Ogar, who is currently on vacation, is said to be visiting her children in the US.
Reports also say that in addition to her premature promotion, Ogar was also offered a generous scholarship to do a PhD in the UK.
Daura also redeployed the chief security officer to President Muhammadu Buhari, Abdulrahman Mani and immediately replaced him with Bashir Abubakar, an assistant director in the Bayelsa State command of the DSS.
Mani has been posted to Ebonyi State.
