An article in yesterday's Metro section incorrectly reported the time and date of a fatal shooting in the 500 block of Kennedy Street NW. It occurred between 3:30 and 4 a.m. Sunday.

A District police officer has been placed on limited duty after his service revolver was taken from him in an incident that followed the fatal shooting of a man during a gun battle in Northwest early Monday, D.C. police said.

The officer, who was off duty at the time, was not involved in the fatal shooting, police said, and apparently no shots were fired after the gun was taken. The .38 caliber revolver has not been recovered.

The incident occurred while Officer David Brown, who is assigned to the 6th District, and another officer, who was not identified, were working as security guards for a private party at the Shaolin Wu-Shu martial arts school, according to police sources.

Dennis Brown, owner of the school at 510 Kennedy St. NW, said the party was sponsored by a local West Indian record store owner. Police said about 300 persons attended the party.

Shortly after 1 a.m. Monday, police said, an unidentified person in a car outside the school began firing shots. During the gun battle that followed, about 20 to 35 shots were fired, and Stephen Jackson, 21, of 4925 Fourth St. NW, who was standing outside the school, was hit once in the chest, police said.

Jackson then staggered to the doorway of the school, where he was pulled inside by the officers, police said. He was taken to D.C. General Hospital, where he died about 6:45 a.m. Monday.

After the gunfire stopped, a fight broke out between Brown and three or four men who grabbed him and took his gun from its holster. They later fled, according to a police report filed about the incident. Brown was not injured.

Brown, a 13-year veteran of the force, has been placed on limited duty pending completion of an investigation, according to officials. Police said Brown had not broken police regulations regarding moonlighting.

Homicide investigators said their investigation of the fatal shooting is continuing. They have no motive and no suspects.

A police source said the shooting apparently stemmed from an argument between rival groups of Rastafarians, a West Indian religious cult whose members are usually identified by a hairstyle of long wiry braids, or "dreadlocks."

"It was Rastafarians involved. That's all that was up there," said a police source. "About 20 to 35 shots were fired from more than one gun. There was probably an automatic weapon involved."

During the gun battle, windows of several business near the school were shattered, but no one other than Jackson was struck. Susie Lewis, an area resident said she was awakened by the sound of gunshots at about 1:30 a.m.

"Bullets were everywhere . . . , " said Lewis. "I saw a lot of people running around. I looked out of my bedroom window and saw Jackson lying on his back."

Lewis and others in the neighborhood said they have complained to police in the past about loud music and small outbreaks of violence when Rastafarians hold parties at the school.
