The accused was identified as Nareerat Varitkitkajorn. She was detained at the airport after customs officials found the drug hidden under the lower compartment of her luggage.
She claimed she borrowed the luggage from a hotel in the Philippines, as her bag was broken and that she did not know that the drugs were hidden inside.
Customs officers did not believe the detainee's claims, saying the drug was meant to be distributed to customers here.
The suspect will be initially charged with smuggling illicit drugs into the kingdom and was sent to the Narcotics Suppression Bureau for further legal procedures.
