An Indian man and an Indonesian man were arrested last Friday morning in a shophouse in Johor, Malaysia, after authorities seized nearly 700 tanks of unlicensed liquefied petroleum gas (LPG), which has been dubbed the biggest case of the year.

After months of investigation, the enforcement unit from the Ministry of Domestic Trade and Consumer Affairs raided the shophouse in Permas Jaya in Johor Bahru where the two men were allegedly selling liquefied petroleum gas illegally, the Sin Chew Daily (Malaysia) reported on Thursday.

Officers recovered a total of 673 tanks of various sizes – 32 12-kilogram tanks, 627 14kg tanks and 14 50kg tanks – with an estimated value of 342,647 ringgit (US$81,756). They also confiscated three lorries with a combined value of 270,000 ringgit.

A preliminary investigation found that the suspects supplied gas to residents in the areas of Masai and Pasir Gudang for the past three to five months.

The two men were detained as the investigation continued.
