The federal government has detected about 54,000 fraudulent payroll entries in its Integrated Personnel and Payroll Information System (IPPIS) through the whistle-blowing policy.
This is according to Babagana Monguno, the National Security Adviser (NSA).
He attributed the discovery to the expansion of the coverage of IPPIS against stiff opposition from some quarters.
He said the implementation of the Treasury Single Account (TSA) in more than 90 per cent of all Ministries, Departments and Agencies (MDAs) of the government has resulted in the consolidation of more than 70,000 bank accounts previously spread across deposit money banks in the country, leading to the monthly saving of about N4 billion in bank charges.
The event was convened to discuss the current security challenges and how corruption is fuelling the problems in the country.
Also in attendance were the President of the Senate, Ahmed Lawan; the Chief of Defence Staff, General Lucky Irabor, and the Minister of Interior, Rauf Aregbesola, among others.
