Pahang Fire and Rescue Service deputy director Morni Mamat said rescuers, with the help of four sniffer dogs, were trying to find them under the debris of a landslide at the Sungai Kabok vegetable farm in the Bertam Valley.
The rescue personnel were not discounting the possibility that the two Indonesians could have fled before the landslide occurred as no one saw them getting trapped in the debris, he told reporters at the disaster operations control centre here.
The search was mounted based on a police report lodged by the employer of the Indonesians, he said.
Morni said 27 fire and rescue personnel, 10 soldiers and 10 Department of Civil Defence personnel were involved in the search.
The mud flood on Wednesday claimed the lives of student R. Punesh, 13, an Indonesian vegetable farm worker Anipan, 48, and a Nepali vegetable farm worker Md Yousuf Miya, 66.
Punesh drowned in the Sungai Terlom in Kampung Raja, Anipan was found dead under landslide debris in the Bertam Valley and Md Yousuf was found dead under landslide debris in Jalan Ulu Merah, Ringlet.
The flood was triggered by heavy rain. Altogether, 203 people from 47 families in Kampung Baru and Bertam Valley had to be evacuated to the Ringlet community hall.
People living along the banks of Sungai Bertam were ordered to move out yesterday when water was released from the Sultan Abu Bakar Dam in stages after the water level at the dam began to rise following the rain.
