Ball, 19, of Haymarket, Va., who was named in eight counts, including conspiracy, interstate transportation in aid of racketeering and possession of pheneyelidine with intent to distribute, and JOseph A. Lykins, 18, of Annandale, named in 17 counts including conspiracy, manufacture of phencyclidine and use of communications facilities to commit a felony.

Also, John R. McGee, 22, of Fairfax County, named in four counts including conspiracy, obstruction of justice and possession of phencyclidine with intent to distribute, and Thomas A. Scoular, 20, of Annandale, charged with three counts including conspiracy and attempt to manufacture phencyclidine.

Jarvins, 31, of Falls Church, charged with conspiracy and interstate transportation in aid of racketeering; Alfred Stuart Jr., 21, of Fairfax County, charged with conspiracy and possession of phencyclidine with intent to distribute, and Dennis White of Haymarket, charged with conspiracy and attempt to manufacture the drug.
