This is even as Abdulahi has said that he was not afraid of being probed by Buhari’s government.
President Buhari’s approval followed a letter written by Abdulahi on August 3, notifying the President of his desire to proceed on voluntry retirement which President Buhari approved on August 14.
The president congratulated the CG for the successful completion of his tenure and service to the country which spanned a period of 6 years.
Titled “Voluntary retirement from the Nigeria Customs Service, the approval read thus: “Dear, Alhaji D.I. Abdullahi. I write to acknowledge the receipt of your letter Ref. No. NCS/ADM/HQ/P. 35802 of 3rd August, 2015 conveying your decision to voluntarily retire from the Nigeria Customs Service with effect from Tuesday, 18th August, 2015.
“I note with appreciation your services to this nation, especially as the Comptroller-General of the Nigeria Customs Service in the last six (6) years.
“Accordingly, I hereby approve your voluntary retirement from the Nigeria Customs Service with effect from 18th August 2015.
“I wish you the very best in your future endeavours.
