A Kampong Thom farmer who went missing from police custody under suspicious circumstances

on January 12 has still not been heard from.

Military police said Eip Thien escaped from their custody, but human rights groups

question whether he really fled and are concerned for his safety.

Chan Soveth, monitor for human rights group Adhoc, said his request to military police

for a report on Thien's disappearance has been ignored.

Adhoc has prepared a complaint that will be filed with Kampong Thom provincial court

if Thien does not reappear by the end of February.
