Amosu and others allegedly stole over N323 million from the accounts of the Nigerian Air Force between 2014 and 2015.
The Economic and Financial Crimes Commission (EFCC) charged Amosu alongside two other officers of the Air Force AVM Jacob Adigun and Air Commodore Gbadebo Olugbenga.
Also charged are some companies; Delfina Oil and Gas Ltd, Mcallan Oil and Gas Ltd, Hebron Housing and Properties Company Ltd, Trapezites BDC, and Fonds and Pricey Ltd.
They had been arraigned before Justice Mohammed Idris on June 26, on charges bordering on conspiracy, stealing and money laundering.
They had pleaded not guilty to the charges.
The judge had granted them bail in the sum of N500 million each with two sureties each in like sum.
At the resumed proceedings, counsel to the EFCC, Mr Rotimi Oyedepo, called his first witness, Mr Mojeed Olatunji, a compliance officer with Skye bank.
Olatunji told the court that the Nigerian Air Force (NAF) had an account numbered 1750013097 with Skye Bank.
He said the account had as its signatories as at January 28, 2014, Air Commodore J.B. Adigun, Air Commodore O.O. Gbadebo and Group Capt. B.O.G. Ifeobu.
He said that Adigun, Gbadebo and Ifeobu were those who had the mandate on the account and on whose instruction monies were withdrawn.
Armed with the statement of the said NAF’s account with Skye Bank, Olatunji took the court through a number of inflow and outflow of cash transactions carried out on the account.
For example, he told the court how N2.4 billion was credited to the account on September 11, 2014, and how this was followed by debit transactions of N959.7 million, N893.2 million and N556.3 million, respectively.
The witness said that the debit was in favour of the NAF Special Emergency Operation account.
The accused were said to have indirectly converted N3.6 billion belonging to the Nigerian Air force, to their own use.
In another instance, the EFCC alleged that Amosu and the others stole over N323 million from the accounts of the Nigerian Air Force between March 21, 2014, and March 12, 2015.
He said the alleged theft was for the purpose of purchasing for themselves a property situated at No.1, River Street, Wuse II, Abuja.
The alleged offences contravened Section18(a) of the Money Laundering (Prohibition) (Amendment) Act, 2012.
Justice Idris further adjourned trial till today, October 21.
