Pol Gen Somyos said a team of police arrested two men carrying yaba pills with an estimated street value of 900 million baht at a gas station on the Phetchabun-Saraburi road.
The suspects are believed to be members of drug network based in Myanmar led by Chaiwat Pornsakulpaisal, known as Lt Col Yi Sae.
Police said the suspects confessed that the drugs were smuggled from Laos and hidden in a warehouse in Nonthaburi province before being sold on to buyers.
Police are attempting to track down other suspected gang members believed to be hiding in Nonthaburi's Bang Bua Thong district.

Mr Nattawat was arrested at a checkpoint in Chiang Mai's Hot district when his six-wheel truck was stopped for a search. Officers found the pills hidden under a load of corn on the back of the vehicle.
