Earlier on Tuesday the Central Bank of Nigeria issued a warning about a fake press release that was shared by her accounts with incorrect information about the phasing out of old naira notes.

Mrs Buhari said in an Instagram post that this was not the first time her accounts had been tampered with:

“This person is a hacker, criminally minded with the intention to continue attacking my reputation through my social media platforms,” the wife of outgoing President Muhammadu Buhari said.

“But I am assuring you that this is the first and last I am disclaiming fake news on my handle.

“It is the responsibility of the security agencies to find out who am I sharing my social media handles with, despite being verified accounts, and take all necessary actions.”

Concerns have also been raised about the spread of disinformation ahead of Saturday’s presidential election.
