An alleged member of a group that calls itself the 5 N O Crew was ordered held without bond yesterday on charges that he was one of four men who robbed a Brinks armored car at Dulles International Airport in May.

At a hearing yesterday before U.S. Magistrate W. Curtis Sewell in Alexandria, FBI agent Harold W. Luker II testified that fingerprints of Kendall Taylor, 19, were found both in the getaway van and on the side of the Brinks armored car and that agents recovered a ring taken in the robbery from a former girlfriend of Taylor's.

Luker also told the court that Taylor and three men indicted earlier in the case are "known associates." Luker testified last month that the three -- Kevin Tyrone Baldwin, 21, Albert Larry Weaver, 30, and Rudolph Hilton Williams, 18 -- were members of a group called the 5 N O Crew, a reference to the neighborhood around Fifth and O streets NW.

Law enforcement sources said last week that Taylor is an alleged member of that group, which has been linked to more than 15 homicides in the area around Fifth and O.

Taylor, who has not been charged in any homicides, is on probation for assaulting a man last December at a Giant Food store on Eighth Street NW.

Carolyn Eaglin, Taylor's court-appointed attorney, said yesterday she knew nothing about the existence of the Fifth and O group and had no evidence to suggest that her client was the leader of it.

Ann Taylor, Kendall Taylor's mother, denied that her son was involved in any criminal group and said that he and others he associated with are "good young men" who often escort elder citizens in the neighborhood around the Giant store.

She said "5 N O" graffiti written around the Kennedy Playground at Seventh and P streets NW were put there by youngsters, not by members of any gang.

Baldwin, Weaver and Williams were arrested June 2 on the corner of Fifth and O. Taylor was arrested Wednesday in the 400 block of M Street NW.

A law enforcement source who has investigated the Fifth and O group has said it includes about 15 young men who are primarily "stickup men" who rob drug dealers operating in the area. Members of the group have been linked to a July 15 drive-by shooting at Columbia Road and Sherman Avenue NW that left two men dead.

The Brinks robbery occurred about 6:40 a.m. May 30 at the Federal Express cargo area as the truck's messenger and guard were returning to the armored car with a shipment. Luker testified yesterday that two men, armed with a "long-barreled revolver" and either a .45-caliber or 9mm weapon, assaulted the two employees, pushed them into their vehicle and threatened to kill them.

Two other men then forced their way into the armored car and removed two bags containing more than $3 million in securities, foreign currencies and jewelry.

Luker did not describe the role Taylor allegedly played in the robbery.

Taylor is being held on charges of conspiracy, obstructing interstate commerce and weapon violations.
