The Senate plenary was on Wednesday disrupted after suspected thugs invaded the chamber and made away with the maze.
The maze is the symbol of authority at the National Assembly and is guarded by the Sargent at-arms without which proceedings can take place or any official dealings can occur.
The incident happened few seconds after Ovie Omo-Agege, a suspended senator, entered the chamber.
Eyewitnesses said about 10 suspected thugs who came to the venue with the senator forced their entrance into the chamber.
The thugs were said to have run out of the chamber with the maze causing pandemonium in the Senate.
They left the National Assembly with the maze in a black SUV.
One of the security personnel at the entrance of the National Assembly said the thugs told him and other officers they were with the senator.
“We tired to stop them but they told us they were with him (Omo-Agege),” he said.
The senators are yet to reconvene as at the time of filing this report.
