A bronze Toyota Grant Hyatt van with a military license plate and a sticker of the 7th infantry division attached to the front windshield arrived at the checkpoint and the officers there signaled the driver to stop but he instead sped away prompting a road chase.

Police and the military later searched the van and found inside about 20 bags packed with ya baa. Two million pills were counted.
The van was found to be rented by a conscript identified as Vichai Rangsirikhet. The licence plate was also a fake.
