According to updates from the ground, the raid is currently being led by the Public Security Bureau. There is no sign of the local Lao police just yet. However, as soon as the word got out, many people inside the building received internal alerts and rushed out, dropping whatever they were doing.
For those still working in the compound, keep your eyes open and evacuate if necessary. Regardless of what they are actually looking for, laying low during these sudden raids is always the safest bet. When making a living far from home, staying well-informed saves you a lot of trouble.
