The Independent National Electoral Commission, INEC, says all materials including ballot papers and result sheets are already at the expected locations across the country.
He said that no house of any Commissioner of INEC was raided as reported in some media.
Professor Yakubu stated that the commissioner whose name was being circulated in the social media was in his office at the time when he gave the briefing.
He also denied the report that six directors were picked up by security operatives, stressing that nothing of such happened.
Professor Yakubu further cautioned politicians against speaking in a manner that would overheat the polity and political atmosphere.
Earlier, he offered his regrets over the postponement of the elections and assured Nigerians that the electoral body under his leadership was working towards conducting credible elections.
