This came following his voluntary return to Nigeria after President Goodluck Jonathan, whom he had blamed his travails in the hands of security and anti-graft agencies on, left office.
The former Chief of Naval Staff reported to the EFCC on Monday after returning from his self-imposed exile on Saturday and was quizzed by the anti-graft agency for about 10 hours, reports Vanguard.
There is no official message yet about the issue by the EFCC.
