A bowser full of high-sulphur contraband diesel has been found and seized by Customs officers.
The discovery was made at Ghajn Dwieli, where the bowser was found to have been driven into a yard which was then sealed up, so that access to it was only possible through a ladder. A pipe led from the bowser to an adjoining garage.
The discovery was made after days of surveillance.
The Customs officers quickly established that the diesel was contraband and it had a sulphur content that was 100 times higher than normal, which is harmful to health and the environment.
The police are investigating.
The Customs Department conducts regular tests of fuel in various localities to ensure that no contraband is used.
There had been reports in the past few days about poor quality diesel being sold from petrol stations. The Resources Authority had said it was taking legal action against the petrol stations.
