The Economic and Financial Crimes Commission (EFCC) has put the immediate former Governor of Edo state, Godwin Obaseki, on its watch list.
The anti-graft agency has also began an investigation into transactions, including contracts awarded during his tenure.
Obaseki left office on November 12 after an eight-year tenure and he claimed that the EFCC planned to arrest him soon after stepping out of office.
His successor, Monday Okpebholo, has just established a 14-member State Assets Verification Committee to investigate his tenure.
Similarly, the EFCC had on November 2 arrested five Edo government officials who served under Obaseki, including the Accountant General, Julius Anelu, over huge withdrawals from the state treasury within a short period of time.
But Obaseki had on November 8 said he was not scared of a probe by the EFCC.
The former governor said he would be willing to submit himself to the anti-graft agency to give an account of his tenure.
