Nigerian Woman Allegedly Tries To Smuggle 5 Lbs. Of Swallowed Heroin Into US STERLING, Va. - Customs officials at Dulles International Airport say a Nigerian woman set an unfortunate record when she allegedly tried to smuggle nearly five pounds of swallowed heroin into the country. Authorities say 52-year-old Bola Adebisi (ah-deh-BEE-see) ingested 180 thumb-sized pellets filled with $150,000 worth of heroin. She's been charged with drug smuggling in federal court in Alexandria. Customs and Border Protection officers became suspicious when she told officers 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. 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.
