This action took place following threats by FIFA, football governing body to ban Nigeria if the situation was not resolved and Amaju Pinnick not reinstated as NFF president.
Stating that they were working on instructions from above, the DSS operatives, who carried out the ejection exercise told Giwa and the staff to vacate the premises.
A few hours after the exercise, Muhammed Sanusi, secretary-general of the NFF, was led to his office by the DSS operatives.
Sanusi has since resumed his duties as head of the football federation secretariat in Nigeria.
President’s office was also cleared in readiness for the resumption of Pinnick who will return to Nigeria on Tuesday.
Pinnick had been away supervising the CAF roundtable symposium on Africa’s performance at the recently-concluded 2018 Russia World Cup.
