A 31-year-old Chinese national was arrested on Monday morning in a hotel room in Kandal province where he was allegedly installing a system for Voice over Internet Protocol (VoIP) extortion, police said.

Provincial Police Chief Eav Chamroeun said yesterday that the suspect, Zhu Chunle, was arrested at the Tranica Hotel in Prek Samroung Village 3 in Takhmao town.

“After we detained him, we . . . interrogated the suspect in relation to his actions,” he said. “We are investigating. We suspect this activity may have involved more people, because he cannot do it alone.”

VoIP-related equipment was found inside Zhu’s room, Chamroeun said, adding that as of yesterday afternoon police were still questioning him.

Uk Hai Sela, head of investigations at the Ministry of Interior’s Immigration Department, said he wasn’t aware of the case.

Last Thursday, 160 Chinese nationals were deported for allegedly operating a VoIP extortion ring in Banteay Meanchey province’s Poipet town.

The deportees were among 215 suspects arrested in August in the one of biggest online extortion raids in Cambodia.
