The ruling All Progressives Congress (APC) National Secretariat in Abuja was on Wednesday taken over by dozens of armed policemen in various patrol vans.
Upon their arrival, the security operatives positioned themselves at the entry and exit points of the secretariat.
According to sources, the policemen stormed the building following a hint that some protesters were planning to stage a march at the premises.
Meanwhile, the ruling party has dismissed insinuations that all was not well with the party after police presence at its headquarters.
The party said the invitation of police operatives was to forestall any breakdown of law and order based on the security report at its disposal.
