"Ketu South again. Seals to ballot bags broke, thumb printed ballots found in the bag. Amidu, the EC official allegedly not cooperating with parties on this," Mr Otchere-Darko wrote.

But in a swift response, the commission said it was not true that the ballots have been thumb printed, urging Ghanaians to disregard the allegation.

"Our preliminary checks from Ketu South shows that there is no iota of truth in the claim made in the post below. No such thing happened in Ketu South. Please ignore it. Our detailed response coming soon," the commission said.
