CHIANG RAI – Thailand’s Department of Special Investigation (DSI) recently led a massive operation against drug trafficking in northern Thailand. Law enforcement officers seized over seven million methamphetamine tablets during two coordinated raids in Chiang Rai and Lampang provinces. This major operation shows the government’s strong commitment to stopping the flow of illegal narcotics across international borders.
Key Takeaways
- Massive Seizure: Thai authorities successfully confiscated over seven million methamphetamine pills (known locally as yaba) in two major operations in northern Thailand.
- Coordinated Efforts: The Department of Special Investigation integrated multiple security agencies, including the military, Mekong River unit, local police, and customs officials.
- Two Key Locations: Raids occurred in Wiang Kaen district, Chiang Rai, and at a specialized X-ray checkpoint in Mae Phrik district, Lampang.
Government Orders Strict Action on Narcotics
The successful raids follow direct orders from the Thai Prime Minister to aggressively suppress illegal drug networks. Minister of Justice Ruthaphon Naowarat instructed all departments under his ministry to take continuous, concrete action against drug cartels. The goal is to completely cut the financial and operational loops of trafficking rings across the country.
Under the guidance of DSI Director-General Yuthana Praedam, law enforcement teams set up a special intelligence sharing network. DSI Region 5 Office Director Somchai Tichai then deployed active field agents to work alongside local security forces. These coordinated efforts were carried out under the official investigative case number 34/2026.
Midnight Patrol Yields Millions in Chiang Rai
The first major operation took place along the natural borders of Chiang Rai province. DSI agents teamed up with the Mekong Riverine Unit, the Pha Muang Task Force, and the Wiang Kaen Police Station. Officers also worked closely with the Office of the Narcotics Control Board (ONCB) and local customs officials.
Together, the combined forces patrolled the border areas near Thai Charoen village in the Wiang Kaen district. During the sweep, officers discovered 17 modified sacks hidden near the patrol zone. Inside the sacks, authorities found a staggering 6,024,000 methamphetamine pills, which were immediately handed over to local police for legal processing.
Secret Truck Compartment Exposed by X-Ray
The second operation happened further south at a major highway checkpoint in Lampang province. DSI intelligence led officers to the Mae Phrik drug search checkpoint on a main northern transit route. Local Lampang police officers were actively monitoring incoming vehicles using a high-tech X-ray tunnel scanner.
The scanning technology flagged a suspicious pickup truck traveling through the Mae Phrik district. Upon closer inspection, officers discovered a hidden compartment built into the back undercarriage of the truck bed. Inside this secret space, smugglers had concealed 964,000 methamphetamine pills, leading to the immediate arrest of two suspects at the scene.
DSI Promises Continued Border Protection
In total, the two interconnected operations removed exactly 6,988,000 yaba tablets from circulation. The DSI released an official statement via the Siam News Crime Report detailing the successes of the joint operations. Officials confirmed that the agency will continue to scale up border surveillance to protect local communities from illegal substances.
By combining the skills of local police, military border guards, and specialized federal agents, Thailand aims to build a stronger shield against international smuggling. Investigators are currently questioning the two detained suspects to trace the source of the drugs and find the ringleaders behind the shipments.
