Authorities have intensified efforts to track former Ako Bicol representative Zaldy Co as the probe into alleged irregularities in public-works projects continues to widen. Interior Secretary Jonvic Remulla confirmed on Monday that international tracking mechanisms are now in motion. “The blue notice is out,” he told reporters during a press briefing.
The Interpol alert, designed to help member countries gather information on a person’s whereabouts, identity, or movements, was activated as Co faces criminal charges tied to controversial flood-control projects. The case, filed before the Sandiganbayan, stems from accusations that public funds were diverted through questionable contracts and large infrastructure allocations coursed through regions such as Oriental Mindoro and Bicol.
Co, who previously led the House Appropriations Committee, had earlier faced scrutiny over budget insertions linked to multi-million-peso public-works packages. He resigned from Congress in 2025 as investigations into the alleged scheme escalated. The Department of the Interior and Local Government has since directed Co and other accused officials to surrender, following the release of arrest warrants connected to a ₱289-million flood-control project.
International law-enforcement cooperation has become increasingly central to the case, with the blue notice now serving as an additional tool for authorities. According to Interpol, the alert supports the “collection of additional information about a person’s identity, location, or activities in relation to a criminal investigation.”
