On September 28, 2026, Singaporean media Lianhe Zaobao reported, citing a report by Cambodian Chinese-language newspaper Jian Zhong Shi Bao, that an immigration police officer in the country, fluent in Chinese, was arrested on suspicion of aiding the illegal entry of foreigners involved in online scams and receiving money. The arrested individual is 30-year-old immigration police officer Phe Phat Pheng. On the 25th, Cambodia's Anti-Corruption Unit (ACU) announced that Phe is suspected of using his official position to facilitate the entry of individuals on the entry ban list, those using forged passports, and foreigners suspected of involvement in online scams. Phe is suspected of being involved in 301 cases of illegal entry arrangements just between January and June 2026, and receiving at least 202,100 dollars (approximately 31.8 million yen). The case emerged during the ACU's investigation into allegations that local administrative officials in Koh Kong province, in the country's southwest, provided premises to an online scam group. According to the ACU, Phe is suspected of working for Cai Youyuan (Cai Youyuan), a Chinese national (codename 'OD') who leads an online scam group. Cai is reportedly the same person as Zhang Jianqiang (Zhang Jianqiang), a Chinese national. Prosecutors at the Phnom Penh Municipal Court of First Instance indicted Phe on charges including abuse of power, conspiracy to commit online fraud, and money laundering. Judicial proceedings are currently ongoing. Zhang is currently at large and reportedly faces charges of bribery, money laundering, online fraud, and organizing/directing online fraud operations.
