He also confirmed that, as of now, no missing person reports had been filed in relation to the incident.

"We still need more time to excavate the site. From what we currently know, one excavator is buried inside. Was there anyone inside at the time of the fire? Further investigation is needed.

"For the next two weeks, until April 15, we need to stabilise the area first. Excavation of the crater will only begin after April 15," he said.

On April 1, a massive fire broke out at a Petronas gas pipeline in Putra Heights, Subang Jaya, causing widespread panic as flames shot into the air.

The intense heat from the flames - visible from kilometres away - melted plastic and metal within a wide radius of the pipeline.

A total of 227 houses and 365 vehicles in residential areas near the pipeline were damaged.
