Thugs suspected to be loyal to the suspended Senator representing Delta Central Senatorial district, Ovie Omo-Agege have invaded the red chambers and forcefully taken away the mace.
They broke into the chambers when plenary was going on, thereby creating serious confusion and tension.
The operation took Sergeant-At-Arms by surprise who tried to reclaim the mace without success.
It could be recalled that Omo-Agege was suspended last week following his role in the electoral act amendment bill seeking to reorder the election sequence.
This development has, hitherto, thrown the Senate, and the entire National Assembly into uproar and fear of what really happened.
The snatched mace is the symbol of authority and the Senate consequently can no longer legitimately hold plenary.
Discussions right now is being held in groups and hush tones as to what might be the next line of action.
This development happened as the Deputy Senate president, Ike Ekweremadu was presiding over the plenary in the absence of the Senate President, senator Abubakar Bukola Saraki who is currently at the World Bank event in the United States.
As at the time of filing this report, the situation is hazy and uncertainty looms large while the Senate has gone into a closed-door session and security at the National Assembly has been heightened.
This is not the not first time such incident would happen the National Assembly, it once happened during the Obasanjo administration when the mace was allegedly taken to Okija shrine.
