A 28-year-old Washington man sought in connection with a fatal shooting last month and at least two other violent crimes was arrested without incident last night on a Northwest street, D.C. police officials reported.

Dwight F. Foster, who had been the object of an intensive, city-wide police search during the past several days, was taken into custody about 6 p.m. as he walked in the 1300 block of First Street NW, according to police officials.

Police had earlier obtained a D.C. Superior Court warrant charging Foster with murder in the March 11 shooting death of Alfred Lunsford, 30, of 225 Tennessee Ave. NE, whose body was found in an alley behind the 1400 block of U Street NW, officials said.

Police said Foster has also been charged in separate Superior Court warrants with armed robbery and assault with intent to kill while armed.

Four separate police units--the homicide squad, the special narcotics task force, the Special Operations Division and the repeat offenders unit--led the search for Foster, whom one official described as one of the most sought after suspects in the city in some time.

On Tuesday night, police surrounded a home on Kennedy Street NW in their search for Foster, but failed to find him.

Foster, of 1119 Orren St. NE, was being held last night in the central cellblock at police headquarters pending his arraignment today in Superior Court.
