South African arrested at Bangkok airport after 17.5kg heroin found in tea and coffee bags

Thai customs officers arrested a South African passenger at Suvarnabhumi Airport after discovering 17.5 kilograms of heroin concealed inside coffee and green tea bags. The seizure took place on 9 July 2026 during a routine inspection by the Investigation and Suppression Division, the Thailand Customs department said.

Journey and discovery

According to the Customs department, the man had travelled from Kuala Lumpur International Airport in Malaysia and was bound for Ivato International Airport in Madagascar when officials searched his luggage and found the narcotics.

Scale and value of the seizure

Customs officials said the drugs were classified as a Category 1 narcotic and were hidden in packets designed to disguise the shipment. The department gave the seizure’s street value as over 7.3 million baht (R3.6 million).

“The Customs department, protecting society, arrested a foreign male passenger for smuggling 17.5 kilograms of heroin hidden in coffee and green tea bags, worth over 7.3 million baht.”

“If the drugs had reached their destination in Madagascar, their value would have been over 22.75 million baht.”

Legal and enforcement context

Thai authorities said the arrest constitutes an offence of importing a Category 1 narcotic into Thailand without permission, in violation of the Customs Act B.E. 2560 (2017) and the Narcotics Code.

The Customs department emphasised its role in both economic and social protection, saying:

“Customs drives the Thai economy while caring for society. This arrest underscores our commitment to protecting communities from the devastating impact of narcotics.”

Aftermath

The suspect remains in custody as investigators pursue leads into the smuggling network.

Thai authorities have intensified anti-narcotics crackdowns and have recorded large seizures of methamphetamine, heroin and illegal cannabis exports while working with agencies such as the Office of the Narcotics Control Board and international task forces.
