Femi Fani-Kayode, an All Progressives Congress (APC) chieftain, has been arrested by the Economic and Financial Crimes Commission (EFCC).
He was arrested at a Federal High Court in Ikoyi, Lagos, and moved to a nearby EFCC office.
The former minister, who was in court over his forgery trial, was walking out after the matter was adjourned till January 24, 2021, when he was approached by an EFCC investigator.
He was subsequently arrested and moved to custody, a week after his earlier arrest.
An EFCC investigator, Mr Shehu Shuaibu, said the ex-Minister of Aviation was being quizzed over false documents.
The anti-graft agency had preferred a 17-count charge of N4.6billion money laundering against Fani-Kayode alongside a former Minister of State for Finance, Nenandi Usman.
Also charged were Yusuf Danjuma, a former Chairman of the Association of Local Governments of Nigeria (ALGON) and a company, Jointrust Dimentions Nigeria Ltd.
The accused who were arraigned before Justice Mohammed Aikawa of a Federal High Court in Lagos had pleaded not guilty to the charges and were granted bail.
Trial had began before Justice Aikawa and witnesses were still being led in evidence, until Aikawa was transferred out of the Lagos division.
The charge was subsequently assigned to a new judge, Justice Daniel Osaigor, and the defendants were scheduled for re-arraignment on October 13, 2021.
