Suspended senator from Delta state, Ovie Omo-Agege, stormed the senate on Wednesday, carting away the mace.
He was said to have sneaked in through one of the glass barricades within the national assembly before carrying the mace.
They broke into the chambers when plenary was going on, thereby creating serious confusion and tension.
Security operatives, according to TheCable ran to the senator to get hold of him but he was shielded by his aides whom he came with.
There is a serious uproar within the national assembly at the moment.
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.
