Bola Adebisi, 52, set a record at the Dulles International Airport, USA, when she excreted 180 thumb-sized pellets of heroin worth $150, 000.
She has been charged with drug smuggling in a federal court.
Customs officers became suspicious on Saturday when Adebisi said she was coming to the U.S. to visit her brother, but couldn't describe him. A routine pat-down found her stomach to be abnormally rigid. An X-ray revealed the pellets and she was taken to the hospital.
Weighing over five pounds, the heroine found on Adebisi is the highest ever ingested by a suspect caught at the airport.
The previous record for an ingested drug seizure at Dulles occurred last year, when another Nigerian was discovered with more than four pounds of pellets.
