The News Agency of Nigeria reports that the incident came barely five days after the governorship primaries that produced former Gov. Ayo Fayose as the party’s flag bearer in the June 21 election.
Although the cause of the incident was unknown, the state’s Police Public Relations Officer, Mr Victor Babayemi, confirmed the development to newsmen.
Babayemi, however, said the incident would be investigated.
He also said that no one had been arrested in connection with the incident.
The party’s Director of Publicity, Mr Kola Kolawole, said people with ‘evil minds’ might be responsible for the incident.
NAN reports that the incident affected a section of the first floor of the secretariat.
An eye witness, who craved anonymity, told NAN that the incident would have been more devastating if not for the early intervention of men of the fire service.
