Three Brazilians have been arrested on arriving at Suvarnabhumi airport and 15.5 kilogrammes of cocaine, worth about 46.5 million baht, seized from their luggage.
The suspects, two men and one woman, had arrived from Brazil on two flights on Monday.
The interception was announced jointly by Customs Department director-general Patchara Anutasilpa, Suvarnahumi airport director Kittipong Kittikachorn and drug suppression officials on Tuesday.
Customs officers first searched the bags of a 27-year-old Brazilian man and a 22-year-old Brazilian woman who arrived from Coribita in Brazil on Qatar Airways flight QR830 about 7am on Feb 14.
An X-ray showed suspicious items in compartments of their three bags. A closer examination found nine kilogrammes of cocaine in the concealed sections. It was wrapped in black plastic and had a street value of about 27 million baht.
