Cambodian police on Thursday arrested an individual whom they believe to be tied to the torture and murder of a South Korean university student allegedly involved in online scams.

Diplomatic sources said Friday that the police had arrested a Chinese national surnamed Li on suspicion of torturing and killing the 22-year-old student near Bokor Mountain in Kampot Province in August, often cited as the base for multiple criminal organizations that employ or kidnap foreign nationals including South Koreans for their scam operations.

Sources said the suspect was apprehended while dining at a restaurant in Phnom Penh in the early hours of the morning. 

A diplomatic official confirmed the arrest but declined to elaborate further because of the ongoing investigation.

The student’s body was found with signs of severe torture on August 8, less than a month after he had informed his family that he was leaving for Cambodia to attend an exhibition.
