The group said it had grown increasingly frustrated with the lack of transparency surrounding the investigation into the Dec 16 incident, which claimed the lives of 31 people, including 13 children.

“The Batang Kali landslide has left an indelible mark on the community, causing immense grief and distress among those who have lost their loved ones and homes,” it said in a statement today.

“As the recovery continues and the community attempts to rebuild, it is imperative that a thorough investigation is conducted to determine the causes of the disaster and to prevent such incidents in the future.”

One of the survivors, who did not want to be identified, urged Amirudin to uphold his responsibility to the people.

“If the investigation report is not delivered promptly and transparently, we are calling for him to step down, allow someone more credible to oversee the situation, and ensure justice for the victims,” the survivor said.

Another survivor, Loh Teng Shui, said he was baffled that the report had not been released, despite Amirudin previously saying it was ready.

“It has been nine gruelling months. My wife and I have been traumatised by the loss of our seven-year-old son.

“Every month, we looked forward to closure, to no avail. We just need closure, and the Selangor leadership has failed to deliver,” Loh said.

The landslide, which occurred at the Father’s Organic Farm campsite in Batang Kali, Hulu Selangor, also injured 61 people.

Preliminary findings by the works ministry showed that tension cracks that stretched along the road running above the hill slope and the accumulation of underground water beneath the campsite had likely caused the landslide.

It was previously reported that a preliminary report had been presented to the Cabinet on Jan 4.

“The report is ready. If there are any applications (requesting for the report), we can issue it in writing,” Amirudin had been quoted as saying on Feb 26, adding that the report had been prepared by the minerals and geoscience department.
