The billionaire was accused of corruption by a civil society group.
According to the reports, embattled owner of Air Nigeria, Jimoh Ibrahim, was not allowed to speak at an anti-corruption conference organised by the Central Bank of Nigeria in conjunction with the Nigerian Police and the London Metropolitan Police.
A civil society group, Civil Society Network Against Corruption (CSNAC), had petitioned the British Government not to allow Mr. Ibrahim speak at the conference, in which he had been pencilled down as a speaker.
