Police dogs "Kai Tuan" and "Kai Wan" sniffed out and helped officers arrest three siblings involved in drug trafficking after they hid over 29,000 methamphetamine pills inside concrete pipe linings in Suphanburi province.
On 2 Feb 2026, Pol. Maj. Gen. Watcharin Prasopdee, Commander of Suphanburi Provincial Police, disclosed that at 11:00 p.m. on 1 Feb, Pol. Col. Peera Asawapiboonpol, Deputy Commander of Suphanburi Provincial Police, ordered the Suphanburi Provincial Police Narcotics Suppression Unit, Team 2, officers from Nong Ya Sai Police Station, and police dogs from the 7th Security Division to investigate and arrest drug traffickers in Nong Ya Sai District. They had received intelligence that a house in Village 2, Chaeng Ngam Subdistrict, Nong Ya Sai District, Suphanburi, was being used to illegally sell drugs without fear of the law.
Officers, accompanied by police dogs, conducted a search, but the occupants fled out the back of the house. The officers chased and arrested them. They were identified as Mr. Somkiat Phosuwan, or Kiat, 59; Mr. Tawee Phosuwan, or Jon, 61; and Mr. Sawing Phosuwan, or Waew, 52—all siblings. Somkiat was still wearing an electronic monitoring ankle bracelet, having been previously arrested on drug charges in 2016 and 2024, and was recently released.
Initial searches did not find drugs, but officers were confident the suspects had hidden narcotics somewhere on the property. They deployed two police dogs—Police Corporal Kai Wan and Police Sergeant Toong Thong (Kai Tuan)—to sniff out the drugs.
The dogs led officers to a suspicious concrete pipe lining. Upon inspection, they found an orange plastic container hidden beside the house, containing two bundles of methamphetamine pills. Inside a bag, they also found two packets of crystal methamphetamine. The dogs further led officers to a cattle pen where drugs were concealed under the cattle feeding trough. The total seized drugs included 29,860 methamphetamine pills and 485.81 grams of crystal methamphetamine.
Additionally, officers found an unregistered 9mm handgun, 72 rounds of 9mm ammunition hidden in a trash bin outside the house, one digital scale, a gray ISUZU pickup truck, and one mobile phone.
Mr. Somkiat, or Kiat, confessed that he purchased the drugs from an unnamed individual residing in Dan Chang District, Suphanburi, intending to distribute them to local users. Police dogs led officers to discover the concealed narcotics during the search.
All three siblings were arrested. Authorities seized the evidence and took the suspects to Nong Ya Sai Police Station for prosecution on charges of drug trafficking, proceeding with legal measures accordingly.
