Karka was prosecuted by the Economic and Financial Crimes Commission (EFCC), Gombe Zonal Directorate, on two counts of criminal conspiracy and cheating. The EFCC alleged that between August 2020 and March 2021, Karka conspired with one Prince Moses Batalu to dishonestly transfer a total of ₦66.7 million from the bank’s account domiciled with First Bank Nigeria Limited without authorization.
The anti-graft agency stated that the fraudulent act contravened Section 61(2) of the Adamawa State Penal Code Law, 2018.
Karka, who was arraigned on November 11, 2024, pleaded not guilty, prompting a full trial during which the EFCC called witnesses and tendered documentary evidence.
Delivering judgment on October 17, 2025, Justice Manji found Karka guilty on both counts and sentenced her to five years in prison, with an option of ₦3 million fine on each count. The court ruled that the sentences will run concurrently.
In addition, the court ordered her to restitute ₦29.8 million to Bonghe Microfinance Bank.
According to the EFCC, Karka’s conviction followed a 2021 audit that uncovered unauthorized transfers from the bank’s account to a non-customer, later traced to her and Batalu. Despite efforts to recover the funds, the money remained unrecovered, leading to the eventual prosecution and conviction.
The EFCC hailed the judgment as another victory in its ongoing campaign against financial crimes and abuse of office in Nigeria’s banking sector.
