Matibag said the latest seizure of defective metal took place in Pampanga, warning that some of the materials pose potential health risks to the public.
A comprehensive report will be issued once the investigation is complete.
The NBI chief discussed the bureau’s findings during a meeting Friday with Justice Secretary Fredderick Vida regarding ongoing operations.
Matibag cited that his meeting with Vida did not cover the pending sedition complaint against Vice President Sara Duterte, clarifying that the matter remains under review by the National Prosecution Service.
“It is pending with the prosecution, the National Prosecution Service. We did not discuss it,” Matibag said.
