Director Nizam Jamaludin said the raid, conducted by a team from the ministry’s Kubang Pasu office at 8.30am, was the result of two weeks’ intelligence gathering.

“A 37-year-old employee was found filling diesel and petrol into the tanks of two trailer lorries, with foreign registration number plates, which had been modified with additional tanks.

“We found 2,148 litres of diesel and 3,982 litres of petrol in the additional tanks.

“The estimated value of the seized items is RM230,300,” Nizam said in a statement today.

He said the man and two 36-year-old Thai men were detained to assist in the investigation under Section 21 of the Control of Supplies Act 1961 (Act 122).

“Consumers may lodge complaints with the ministry via the Op Kesan 2.0 special complaint line at 012-6654292, the e-complaint portal at http://e-aduan.kpdn.gov.my, or at any nearby ministry office,” he said.
