The retired Air Force officer was also detained by the anti-graft agency over his alleged role in the arms procurement fraud.
SaharaReporters reports that Amosu is being investigated amongst other acts for allegedly authorizing the purchase of two helicopters without functional rotors.
The online journal quoted a source to have disclosed to it that the suspect compelled two Air Force officers to fly in one of the helicopters after the craft was equipped with a rotor that was taken from an unserviceable Russian-made helicopter gunship.
The air force officers died in a crash near Yola, the capital of Adamawa State, because the rotors fitted on their chopper was too heavy.
According to the report, EFCC investigators had so far traced nine luxury homes to Amosu, including an imposing property in GRA, Ikeja, Lagos State.
It would be recalled that Amosu was among retired and serving military officers ordered by President Muhammadu Buhari to be investigated by the EFCC.
