According to the officers, they intercepted the bus which was carrying passengers and goods from Kumasi to Aflao at Labour, one of the busy bus terminals in Kumasi on Friday.
The officers said they found 117 prepaid meters hidden in the air-conditioning unit and other compartments of the bus.
The officers later impounded the bus with all passengers onboard and conveyed it to the Ashanti Regional offices of the customs division.
The officers have begun investigations into the incident.
Meanwhile, officials of the Electricity Company of Ghana in the Ashanti Region have also begun inspecting the meters to ascertain their origination.
“If you need a meter, go to the ECG office… if you use an illegal meter, we will catch you and when we catch you, we will fine you,” Grace Garshon, the Ashanti Regional Public Relations Officer of the ECG, said
