The Metropolitan Washington Airports Authority has decided to place a Metro station at Dulles Airport above ground, rather than below.
Federal and local agents across two continents joined forces to arrest seven people on Thursday. Two of the suspects arrested live in Maryland and one lives in in Virginia.
U.S. Attorney Neil MacBride says they're accused of smuggling heroin into the U.S. from west Africa.
"This was a international drug trafficking ring headquartered in Ghana, West Africa that was able to recruit Ghanian citizens in the Northern Virginia area, in Alexandria, to serve as couriers," MacBride says.
MacBride says the investigation is part of a new push by his office to focus on international trafficking rings -- a campaign that is putting an end to operations while they're still small.
"It's significant that DEA was able to detect and dismantle this drug ring before they set up an even broader distribution network across the U.S.," MacBride says.
Dulles Airport is becoming an increasingly popular entry point for drugs entering the country, he adds.
