Manila: Philippines immigration agents, backed by troops, have arrested more than 300 Chinese for alleged cyber crimes, a week after a similar number were detained during a raid linked to investment fraud. The Bureau of Immigration late Tuesday said 324 Chinese nationals were arrested in Puerto Princesa City on Palawan island during Monday’s operation. “Aliens were reportedly rounded up in eight hotels and establishments where they were caught in the act of doing their illegal activities,” the bureau said in a press release.It quoted Immigration Commissioner Jaime Morente as saying the detainees, most of whom appeared to be undocumented, will undergo deportation proceedings.

Agents swooped on an office building in the capital Manila to take four suspects into custody in connection with the 100 million yuan (USD 14 million) scam, but said they stumbled on many more “conducting illegal online operations.” Monday’s raids in Palawan stemmed from reports made by local officials about the presence of illegal Chinese workers in Puerto Princesa.
