District of Columbia police have arrested a 29-year-old unemployed Washington man in connection with one of the "Butch and Sundance" robberies of 11 Northern Virginia pharmacies in the past four months.

Wilbert Lee is being held as a fugitive from justice in the July 19 armed robbery of the Boulevard Medical Center at 8301 Arlington Blvd., Fairfax. Lee was arrested Friday at 3:45 p.m. as he got into his car near his home at 1220 12th St., NW, said Sgt. William McGill, supervisor of the District fugitive squad.

Lee is the third suspect arrested in connection with a spate of robberies of small, independent pharmacies. In each case, two robbers demanded morphine-based, controlled drugs and emptied the pharmacies' cash registers and safes, victims and witnesses have reported.

In each case, the robbers, one black, the other white, were "professional and calm," said witnesses.

The racial mix of the robbers and their technique prompted authorities to dub them "salt and pepper," or "Butch and Sundance."

Earlier this month, police arrested two unemployed men, Terry Lee Snow, 30, and Calvin Hewitt Fulmer ii, 28, in connection with the robberies. Both men were charged with the Boulevard Medical Center robbery. Snow also was charged with the Aug. 7 holdup of the papothecary of Burke, 8966 Burke Lake Rd.

Snow and Fulmer are white. Lee is black.
