The incident unfolded at the Pattani Green Biomass Power Plant, located in the Lipasango sub-district of Nong Chik district. According to initial reports, the assailants infiltrated the industrial compound through its rear section in the early hours of the morning. Brandishing firearms, the intruders systematically rounded up the plant’s operational personnel and on-site security guards, forcing them to gather at the facility’s front entrance. Shortly after securing the staff, a loud explosion echoed from within the plant compound, prompting an immediate emergency response.

A ranger task force was alerted to the breach at approximately 12:40 a.m. and swiftly mobilized to the scene. Responding units immediately established a wide security perimeter around the industrial site, deploying personnel to set up strategic checkpoints and roadblocks on all access routes. The rapid deployment of the task force was aimed at containing the situation, preventing the suspects from escaping the immediate vicinity, and ensuring the safety of the surrounding communities.
