The Philippines National Bureau of Investigation (NBI) shut down another alleged illegal online gambling operation this week. After obtaining a search warrant from a Tarlac court, the bureau swooped in on a Pampanga province home where Chinese nationals were reportedly working out of.

Local news is reporting the NBI was tipped off that there might be an illegal set up by a November 29 intelligence report, covering activities run without licenses.

In total, 12 Chinese nationals were arrested, with one more still being searched for, as he was not in the building at the time of the raid, according to media reports.

In addition to the arrests, government agents seized 13 computers, 15 mobile phones, and some networking equipment. NBI Digital Forensic Laboratory agents confirmed the devices were being used to communicate with clients, handle funds, and provide maintenance on the operation.
