“So far today, we have been able to seal four petrol stations over various offences bordering on hoarding and under-dispensing.
“The exercise has been successful. We have monitored more than 15 filling stations.
“We will continue to intensify our surveillance to ensure sharp practices by the petroleum marketers are brought to the barest minimum,” he said.
He advised marketers against hoarding products, while urging the consumers not to indulge in panic buying assuring that the situation would soon normalise.
Goziem also advised consumers to report any sharp practices by the marketers to the regulatory agency for appropriate sanction. (NAN)
