Hulu Selangor police chief Supt R Supramaniam, operation commander at the location of the landslide, said based on initial reports by the Public Works Department (JKR), there was still groundwater flowing in the affected area.

“JKR will be using alternative roads as temporary routes. The contractor is still carrying out works to cover the area with canvas to avoid further landslides.

“For the time being, the affected area has been categorised as a Red Zone and all 340 residents from 64 families have been ordered to vacate their houses,” he told a media conference here.

He said the landslide had caused the formation of a huge hole, measuring 10 to 15 metres deep and over 600 metres in radius.

He said JKR would submit a full report on the landslide in about four days.

Meanwhile, the Hulu Selangor District Council will evacuate residents accommodated at Sekolah Rendah Agama Serendah to a different location if another landslide occurred in the area.

“So far, 22 of the 64 families involved have yet to register with the Welfare Department,” said Supramaniam.

A resident Muhammad Fareez Hanudin, 21, who was returning home on his motorcycle at the time of the landslide, injured his hand and leg, while a food stall and 10 cars were destroyed when it fell into a deep hole created by the flowing mud.
