YANGON, Dec. 12 (Xinhua) -- Myanmar authorities have seized 1.3 million stimulant tablets in Sittway, Rakhine state, said a release from the Central Committee for Drug Abuse Control on Wednesday.

The stimulant tablets worth 3.9 billion kyats (2.51 million U.S. dollars) were discovered along with soap bars in 33 cardboard boxes loaded on a three-wheeled motorcycle when it was intercepted near Yay Chan Pyin port on Tuesday.

Along with the driver, another suspect who had loaded the boxes was also arrested shortly after the driver's disclosure to the police.

An investigation into the case is underway and regional police have filed against the two suspects under the narcotic drugs and psychotropic substances law.
