Early in the morning on June 18, a message from an unknown account slipped into the TikTok inbox of a flight attendant in Bangkok with a series of questions: ¡°Are you flying to Australia? Do ?you do carry-for-hire? What is your rate?¡±

The 30-year-old, who flies for a regional budget carrier, ignored the message and forgot about ?it ¡ª until ?Tuesday, when a Thai Airways flight attendant was charged with importing more than one kilogram (2.2 pounds) of ?heroin into Australia hidden in several tote bags.

The rare detention of a national airline cabin staff has triggered alarm in Thailand, raising questions about security measures at airports and concern that international trafficking networks are targeting air crew in their attempts to get illicit drugs to ?lucrative markets beyond the Southeast Asian nation. Thai Prime Minister Anutin Charnvirakul on Friday will convene a meeting of the top national anti-drug committee, which includes ?the chief of the main anti-narcotics agency, senior ministers as well as police and military officials.
