The second Radio Free Asia reporter in as many months has gone into hiding, this time following a death threat by telephone for reporting on illegal logging.
Lem Pichpisey, who was investigating reports of illegal logging outlined in a Global Witness report earlier this month, was hiding along the Thai border, where he spoke to VOA Khmer Monday.
"I'm concerned about my safety," Lem Pichpisey said.
He criticized Prime Minister Hun Sen for remarks in May aimed at another RFA reporter, Keo Nimuol, who also went into hiding.
Lem Pichpisey said he received a phone call Saturday, in which an unnamed caller told him, "Don't be nasty about the illegal forest report."
"Be careful," the caller said.
