The Department of Petroleum Resources (DPR) in Jos, Plateau State, has sealed off at least 20 illegal fuel stations.

Operations Controller of the DPR Jos field office, Jerome Agada, confirmed this to journalists on Friday.

According to the officials, some of the retail outlets visited did not have the required permit to operate while some do not conform to technical and electrical specifications required as well as structural construction for such facility.

Meanwhile, 18 persons were also arrested for operating the various illegal retail outlets.

Agada noted that the exercise was part of measures to ensure sanity in the petroleum retail outlet business as well as compel operators to comply with rules and regulations in providing efficient services to the public.
