A Fairfax County man died Saturday evening of injuries suffered in a fight outside a bar, and an arrest was made, the county police said.

They said Harold Garnett, 27, of Centreville was found with upper-body wounds about 2:15 a.m. Saturday outside Velocity 5 in Centreville, after authorities received a call about a possible stabbing.

Vidal Flores Cuchillas, 38, of Centreville, was arrested and charged with malicious wounding, the police said. They said authorities would discuss amending the charge after Garnett's death.

Police in Fairfax County said they think up to 50 people witnessed two fights, including the one in which Garnett was killed.

Authorities said they think there was a second fight that involved Cuchillas and two others who were not identified. They said the men also assaulted a 26-year-old man before running from the scene.

There were very vague descriptions given by police of the other two suspects. They are said to be Hispanic men in their mid- to late 20s with thin builds.

In a statement, detectives in Fairfax said they believe the two men were "active participants in the fight, but are only suspects in the second assault case, and not in Garnett's murder."

Anyone with information is asked to call 703-246-7865.
