The Nigerian Ports Authority has debunked the claim by a whistle-blower, John Okupurhe, that it operated a secret Unity Bank account, with a balance of $1bn in violation of the Federal Government’s Treasury Single Account policy.

This was as Okupurhe demanded payment of commission on the allegedly exposed money from the Office of the Attorney General of the Federation in line with the Federal Government’s whistle-blowing policy.

On Monday, a coalition of civil society organisations in the South-South threatened to sue the Federal Government over the refusal to pay Okupurhe his commission for exposing the alleged secret bank account with $1bn balance.

The civil society organisations, under the auspices of South-South Anti-Corruption Watchdog, on Monday in Benin City, Edo State, vowed to expose those behind the $1bn and ensure that Okupurhe was paid his commission.
