Onyia Chika Steven was arrested with 68 blank GTB ATM cards, according to a statement by the Economic and Financial Crimes Commission (EFCC).
Mobile phones, and a Lexus car were also recovered from him when he was arrested by the NDLEA last week.
After he was transferred to the EFCC, preliminary investigation turned up two more blank ATM cards when a search warrant was executed at his residence.

The unnamed banker is reportedly currently helping with the investigation.
The anti-graft agency said the suspects will be charged to court as soon as the investigation is concluded.
