Police will be calling up more individuals to help with the investigations into Friday's landslide tragedy at the Fathers' Organic Farm campsite, Gohtong Jaya in Batang Kali, Selangor, including survivors.

Hulu Selangor District Police chief Suffian Abdullah told a press conference today this may be done in "a week or two” considering the condition and trauma experienced by the survivors, who are mostly from Sekolah Jenis Kebangsaan Cina (SJKC) Mun Choong.
