On July 5, 2026, Customs officials at the Thai-Myanmar Friendship Bridge Border Crossing No. 1 in Mae Sai District, Chiang Rai Province, along with officers from Mae Sai Police Station, jointly announced the arrest of one Myanmar national and the seizure of a large quantity of narcotics worth over 74 million baht.
Key Takeaways
- Massive Narcotics Seizure: Authorities confiscated 600,000 methamphetamine pills and over 111 kilograms of ketamine.
- Large Financial Value: The total street value of the illegal drug shipment is estimated at 74 million Baht.
- Suspect Arrested: A 41-year-old driver from Myanmar was detained at the Mae Sai border checkpoint during inspection.
Customs officers noticed something strange about a motorized tricycle arriving from Tachileik. The vehicle carried numerous plastic baskets covered by a large tarp. Despite looking like an empty load, the tricycle seemed heavily weighed down.
Officials ordered the driver to stop for a closer look. Officers removed the plastic baskets and discovered hidden packages underneath. The initial physical search quickly revealed a massive stash of illegal narcotics.
According to Thai Customs Officials, the seized contraband included 60 blocks of methamphetamine. Officers also discovered 107 packages containing ketamine. The total weight of the ketamine reached exactly 111.815 kilograms.

Driver Claims Innocent Transport Job
The police identified the arrested driver as a citizen of Myanmar. He resides in the Shan State region just across the Thai border. Investigators questioned the suspect immediately after finding the hidden drugs.
The driver claimed he did not know about the illegal narcotics cargo. He told police that another man hired him to transport the baskets. The suspect allegedly received a payment of 10,000 Baht for the delivery job.
The employer had borrowed the tricycle earlier to load the goods himself. They met near the border exit before the journey started. The driver then drove the vehicle across the bridge toward Thailand.
Thai authorities charged the suspect with smuggling illegal drugs into the country. He faces severe legal penalties under strict national anti-narcotics laws. The suspect remains in police custody at the local station.
Law enforcement agencies are working together to expand the investigation. They want to identify the main organizers behind this shipment. Border security remains high to prevent further smuggling attempts.
