Both Philippine Drug Enforcement Agency chief Anselmo Avenido and Philippine National Police Deputy Director General Edgar Aglipay, head of the PNP task force against illegal drugs, refused to discuss the new arrests to avoid jeopardizing ongoing operations.
The two arrested Chinese are now undergoing interrogation, sources said.
Avenido and Aglipay both conceded that last Saturdays drug bust dealt "a big blow" to illegal drug operations in the country.
Meanwhile, Senior Superintendent Roberto Rosales, Cavite police director, told The STAR that at least 500 grams of shabu were seized by a joint police-PDEA team in an abandoned house at BF Resort in Las Piñas.
The shabu seizure resulted from the disclosures of Wilson Li, one of the four Chinese suspects arrested during the Cavite raid.
Rosales said charges are being readied against Li and his compatriots Leandro Go, William Chen and Daniel Co, and their Filipino cohorts Arnel Villaser and Michael Pandag.
