According to an Economic Financial Crimes report, at least eight former ministers of former President Muhammadu Buhari have been invited due to claims of potential corruption.
It was discovered that the invitation letters asked the former top government officials to appear and discuss how they used funds allotted to their ministries on specific projects while they were in charge at their respective posts.
Before Abdulrasheed Bawa's resignation as head of the committee, the letters, it was learned, were sent to the former ministers.
Several sources within the commission said that the anti-graft agency had started an investigation.
The source claimed that apart from the former minister of women's affairs, Pauline Tallen, who was invited last week over an alleged N2 billion scam and "part of the money allegedly diverted from the African First Lady Peace Mission Project," around seven other people have also been invited.
Recall that the commission last month apprehended Sale Mamman, a former minister of power under the previous president Buhari, in connection with an alleged N22 billion scam involving electricity installations.
As part of the same investigation, it was discovered that Muhammad Maigari Dingyadi, the previous minister of police affairs, had also been called to testify regarding the administration of the Police Trust Fund.
The source, who spoke on the condition of anonymity, said Dingyadi will respond to claims that he had purchased used cars for the Nigerian Police and passed them off as brand-new.
"Well, I haven't seen the letter and I'm not aware of it. Dingyadi, the minister of police affairs, informed one of our correspondents over the phone that they might have sent it to the office and that he would check with them."
