Nigerian police have arrested suspended Senator Ovie Omo-Agege after he allegedly led a group of protesters to steal the Senate’s mace.

Several intruders rushed into the upper chamber of the country’s parliament, grabbed the ceremonial staff during a session and fled with it.

The Senate’s spokesperson accused Mr Omo-Agege of leading the “armed hoodlums”, saying they had committed treason.

Mr Omo-Agege was recently suspended because of a row over comments he made during a debate on electoral reform.

The suspension was to serve as a deterrent to other senators who might wish to take the Senate to court over internal matters.
