The military was not spared by the NSO either, the agency investigated Col. Aliyu Mohammed of the DMI and found him to be complicit in an import license racket, he was subsequently compulsorily retired from the army after six months in detention. During this period, Aliyu's friend and superior, Ibrahim Babangida also came under the scrutiny of the NSO, this arose because of a business dealing he and his brother in-law Sunny okogwu were involved in. Babangida and his brother in-law had wanted to set up a military hardware company called 'Black Gold' in Kaduna. The then military governor of the state, Air Vice-Marshal Usman Mu'azu wrote to the Supreme Military Council (SMC) explaining that the project was a national security risk and requested guidance on the matter. The SMC then referred the matter to the NSO for investigation.
