A former Director of Finance and Accounts at the Nigerian Air Force(NAF), Air Commodore Salisu Abdullahi Yushau (retd) has testified before a Federal High Court in Abuja, that all former Air Chief Marshals diverted N558.2 million monthly from funds meant for the payment of salaries of NAF officials. Yushau made this known at the continued trial of the immediate past Chief of Defence Staff, Air Chief Marshal Alex Badeh, who allegedly siphoned over N3.9 billion from account of the force in 2013. Yushau, who started his Evidence-In-Chief on March 16, told the court that, “The practice of setting aside the N558.2 million was already there, even before I was appointed as the Director of Finance in 2010.I gave the Chief the complete brief of the financial position of the Nigerian Air Force when he was appointed. From then he took control of the expenditure of the balance of N558.2 million which we monthly deducted from the salary account.” Yushau further said the system was effected when he served under former Air Chief Marshal M.D. Umar from October 2010 to October 2012. Umar is equally under the investigative radar of the Economic and Financial Crimes Commission(EFCC).
