The party’s state commissioner, Ab Halim Tamuri, called on parliamentarians to raise the matter in the lower house as many residents were affected.

“This is not just a state-level issue but a national matter,” he said at a press conference in Puchong.

Halim’s push for the matter to be debated in Parliament comes a day after it was reported that opposition assemblymen in Selangor were set to raise the issue in the upcoming state assembly sitting on July 7.

Yesterday, Malaysiakini quoted Halim as saying that the authorities’ final report on the incident was lacking and relied heavily on an internal investigation committee.

He also said the report raised more questions than answers.

On April 1, a gas pipeline in Putra Heights burst which saw flames soaring over 30m high with temperatures reaching up to 1,000 degrees Celsius.

Firefighters took nearly eight hours to extinguish the blaze which left a 10m-deep crater, measuring 21m by 24m.

While there were no fatalities, some 150 victims had to seek treatment at hospitals.

On Monday, Selangor police chief Hussein Omar Khan said the authorities had classified the probe into the incident as “no further action” after investigators found no evidence of negligence or sabotage.
