Metro Manila (CNN Philippines, December 14) — The government on Thursday deported 180 Chinese nationals arrested during a raid in a Philippine Offshore Gaming Operator (POGO) hub in Pasay City, an immigration official said.

Immigration Commissioner Norman Tansingco said the undocumented Chinese nationals found within the premises of Smart Web Technology Corp. were linked to human trafficking such as prostitution and labor exploitation.

“Their activities are contrary to local laws and public interest, hence making them undesirable aliens,” Tansingco said.

The immigration bureau included the 180 foreigners in the list of blacklisted aliens.
