Hanoi police arrested a transgender television star for allegedly attempting to resell ten ecstasy pills.
Tram Anh was arrested half an hour after midnight on Monday with the pills which amount to around 2.6 grams of the drug.
She said a person named Hung had ordered the pills and she had gone to pick them up from a person named Tuan for VND2 million (US$94).
She planned to make a VND500,000 profit on the deal.
The police say they arrested her with an accomplice named Nguyen Huu Dat, 19, during the transaction.
Anh was born a boy under the name Nguyen Van Hieu but grew her hair long and began to act and dress like a girl in the first grade.
She joined a series of transgender club and fashion shows in high school, before participating in Vietnam Next Top Model and Vietnam Idol -- the local adaptations of US reality contests -- in 2010.
During the competitions, she described herself as a dance school dropout.
Though she didn't make it far in the reality show competitions, Anh attracted tens of thousands of followers on Facebook.
Early this year, she signed a VND1 billion ($47,150) contract with a sex change clinic which offered to provide her in-kind service in exchange for serving as its image ambassador for five years.
Vietnam has some of the world’s toughest drug laws.
Those convicted of smuggling more than 600 grams of heroin or more than 2.5 kilograms of methamphetamine face the death penalty.
Producing or selling 100 grams of heroin or 300 grams of other illegal narcotics is also punishable by death.
