Houston ? Two U.S. air marshals face federal drug charges accusing them of using their positions to smuggle narcotics through airport security and onto planes for transport, federal prosecutors said.

Shawn Ray Nguyen, 38, and Burlie L. Sholar III, 32, both of Houston, were arrested Thursday after an informant delivered 33 pounds of cocaine and $15,000 in “up front money” to Nguyen’s Houston home, authorities said.

According to a criminal complaint, authorities began investigating Nguyen in November after receiving a tip that he was involved in selling drugs.

Authorities said Nguyen recruited Sholar and the two planned to smuggle 33 pounds of cocaine aboard a plane bound for Las Vegas in exchange for $67,500.

Both men face 10 years to life in prison and a $4 million fine if convicted.
