A former British flight attendant is facing charges after police say she smuggled synthetic drugs made of human bones.

Charlotte May Lee, 21, is facing charges after Sri Lanka police caught her allegedly smuggling over 100 pounds of a dangerous synthetic drug made from human bones.

BBC News reports that police detained Lee at Bandaranaike Airport in Colombo earlier this month. She had been allegedly transporting suitcases filled with “kush.”

The New York Post reports that the drug came from West Africa and causes roughly a dozen deaths each week in Sierra Leone.

Lee reportedly claimed that someone planted the drugs in her luggage without her knowledge, her attorney, Sampath Perera, told the BBC.

On Wednesday, she told Mail Online that she “had seen them [the drugs] before,” and claimed “someone must have planted it” while she left her hotel in Bangkok for the night.

“So I left my bags in the hotel room and headed for the night out. As they were already packed, I didn’t check them again in the morning.”

Lee had been working in Thailand, but her 30-day visa was close to expiration. While waiting for her visa renewal, she decided to fly to Sri Lanka for three hours, according to her lawyer.

Meanwhile, Sri Lankan police have alerted the public to a significant rise in the influx of drugs entering the country from Bangkok.

“Another passenger who had left Bangkok airport, almost at the same time, was arrested in another country. We arrested this lady [Lee] based on profiling,” a Sri Lanka customs officer told the BBC.

Lee faces a possible 25-year sentence if found guilty.
