Watana Buapha, 26, was arrested at 1.30am under a U-turn bridge near the entrance to a community on Prasert Manoonkit Road in Chatuchak district.
Bangkhen police chief Pol Col Amnart Intharasuan said there was a tip about teenagers taking drugs in the area. Police saw Watana fleeing on a motorcycle but managed to stop him.
There were 30,000 meth pills in a bag in the bike’s front basket. A search of his house and a condo in Nonthaburi uncovered more drugs.
Watana purportedly admitted to police he’d been hired to collect the meth on Prasert Manoonkit Road and deliver it to a location on Kanchanapisek Road in Bang Bua Thong.
He knew his employer only by the nickname Ong.
