The police have arrested Ovie Omo-Agege, a senator from Delta state, who led some unidentified persons to cart away the mace of the Senate.
He was arrested around 1:50pm on Wednesday, not long after the senate adjourned.
He was driven away in a black sport utility vehicle (SUV) in the company of three other police officers.
Omo-Agege had returned to the green chamber barely one hour after the mace was carted away, but was not quizzed or apprehended immediately.
It was learnt why the police waited for the plenary to be over before picking him because as a senator, he has immunity against arrest, while in the chamber.
As he was being led away, the senator refused to respond to questions from journalists regarding where the mace was, or why he had come earlier with some thugs to seize it.
A security source at the National Assembly told newsmen that Omo-Agege would likely be charged to court and prosecuted for treason.
Earlier, the mace which is the symbol of authority of the Senate was snatched by some unidentified men.
Our correspondent at the National Assembly reports that the men barged into the Chamber of the Senate, during plenary, pushed away the Sergeant-at-Arms positioned at the entrance and carted away the mace.
It is unclear if the men have succeeded in leaving the National Assembly complex but at the time of this report, the mace has been taken away from the chamber.
The drama coincided with the protest at the National Assembly against the suspension of Senator Ovie Omo-Agege, APC- Delta Central.
The Senate has described as a treaonable felony, the action of suspended Senator Ovie Omo-Agege who led unidentified men to the chamber of the senate to snatch the mace which is its symbol of authority.
Spokesperson of the Senate, Senator Aliyu Sabi Abdullahi, described the action as an attempt to overthrow an arm of government, describing it as treason.
“Today, some hoodlums led by suspended Senator, Ovie Omo-Agege, walked into the Senate plenary and seized the symbol of authority of the Upper Legislative Chamber, the mace.
“This action is an act of treason, as it is an attempt to overthrow a branch of the Federal Government of Nigeria by force, and it must be treated as such.
“All security agencies must stand on the side of due process and immediately mobilize their personnel to retrieve the mace and apprehend the mastermind and the perpetrators of this act.
“This action is also an affront on the legislature, and the Leadership of the House has come to express their support against this action.
“The Senate is now in an Executive session. An updated statement will be released immediately after the closed door session,” he said.
