Three Minnesota women were arrested on Tuesday after customs agents found more than $3 million worth of illegal drugs in their luggage.
The women were traveling from Japan to O'Hare International Airport in Chicago with nearly 70 pounds of opium concealed in bags of tea leaves, according to the U.S. Customs and Border Protection.
Pa Yang, 57, and Mai Vue Vang, 58, both of St. Paul, and True Thao, 52, of Brooklyn Center, were charged with one felony count of manufacturing and delivery of a controlled substance, the Star Tribune says.
They are expected to make their first court appearance in Chicago on Wednesday, reports say.
This isn't the first time a Minnesota woman has been arrested for bringing drugs into the United States from Asia this year.
Last month, a Walnut Grove woman traveling back to Minnesota from South Korea was caught with more than 37 pounds of opium and 3,500 methamphetamine pills at the O'Hare airport.
In March, a woman traveling from Thailand was caught with 33.5 pounds of opium powder at the Minneapolis-St. Paul International Airport.
