A Principal Staff Officer at Nigerian Air Force(NAF) Headquarters implicated in the $2.1 billion arms deal and put under house arrest at Niger Barracks, Abuja has returned N66 million of the N90 million, allegedly traced to him, to the Economic and Financial Crimes Commission (EFCC). The senior officer has been released from detention and asked to go and look for the balance of the money. There are however reports that the other officers being detained by the NAF High Command, on behalf of the EFCC, were not allowed the privilege because they had refused to cooperate fully with the anti-graft interrogation team even though some had returned exotic cars and other valuables. Meanwhile, the wife of a former Chief of the Air Staff, Mrs. Lara Amosu, detained overnight by the EFCC, has been released on bail. The money allegedly recovered from Amosu’s house in Lagos has been kept as exhibit to be used when the trial of suspects in the arms deal begins.
