Oko who spoke to newsmen at the Nasarawa State Criminal Intelligence and Investigation Department (CIID) in Lafia, said that he carried out the theft alone with no inside help:

“As a cleaner, I knew where all the keys were kept. I single-handedly carried out the operation because I have been working as a cleaner in the bank for the past 10 years and my eyes had been on one of the keys to the vault, where the bank used to keep all its money.

As a cleaner, my attention was not only on the keys, but on how I will carry out the operation successfully without being caught by either the security or any staff of the bank.”

The suspect added that he stole the money without the knowledge of the bank workers, adding that he had access to all the foreign currencies in the bank as he knew where they were kept.

“As a cleaner, I knew where all the secret files were kept and where the bank kept its keys where you can have access to dollars, Nigerian currency and all other currencies.”

Blaming the harsh economic situation in the country for his actions, Oko said that he had never been involved in a criminal act before now.

“The devil of economic recession pushed me into the crime; I have never committed a criminal act before, luck ran out on me and I was caught in the process,” he stated.
