Nigerian Police on Wednesday arrested Senator Ovie Omo-Agege over mace theft at the National Assembly.
Mr Omo Agege was picked immediately after plenary by policemen who ushered the Senator into a waiting pickup van.
The lawmaker had been suspended by the Senate for 90 days last week.
He, however, attended the plenary today along with about 10 thugs.
The Senate accused him of leading the armed men who stormed the chamber and snatched the mace while plenary was on.
