Two men, described as members of a violent drug gang operating in the District, were arrested yesterday in North Carolina and charged with murder in the execution-style slaying of an 18-year-old Northwest Washington man, federal authorities said.

The arrests in Conover, N.C., 50 miles north of Charlotte, ended a seven-month search that involved the FBI, D.C. police and North Carolina authorities, officials said.

The two men -- Dion Nash Sidberry, 22, and Scottie Antonia Lattimore, 23 -- were described by the FBI as members of a "youth gang that is involved in homicides, shootings and drug dealing."

They were wanted in the May 19 slaying of Antonio Darnell Broady, 18, who was shot once in the head while standing outside his house on the 100 block of R Street NW.

D.C. police declined to elaborate on the FBI statement. The U.S. Attorney's Office, reached late in the day, was unable to provide any information on the arrests, the suspects or the alleged gang of which the two were said to be members.

Conover authorities said Lattimore and Sidberry, who also is known as "Twin," were living under assumed names in nearby Newton. Lattimore has relatives in North Carolina, and federal authorities had tracked the two to the state.

Yesterday, the FBI and local police staked out an apartment where the two had been living. Authorities in North Carolina said Lattimore and Sidberry spotted the unmarked cars about 10 a.m. and sped away, beginning a chase that took them to Conover.

The car was later abandoned, and Lattimore was arrested after a foot chase. Sidberry fled into the woods and eluded police for about three hours before police, using tracking dogs, found him in an unoccupied house.

The two men, both of whom face charges of first-degree murder, were arraigned yesterday before a U.S. magistrate. They were turned over to the U.S. Marshals Service, which will return them to the District.
