LOS ANGELES -- A juvenile is under arrest in connection with the death of an anti-gang activist who was killed during a confronted by a tagger in the Mid-City area.

Police say the victim, Ronald "Looney" Barron, was killed Sunday after he left a bar in central Los Angeles and noticed the boy defacing a wall.

Police say Barron confronted the tagger, who shot the 40-year-old multiple times.

He was pronounced dead at a hospital.

Police would not release the name of the suspect due to his age.

They say he is not a gang member, but is a known tagger.

His age was not immediately released.

A former member of the Mansfield Crips, Barron worked for the past decade for Amer-I-Can, which runs a program in which former gangsters counsel youth to avoid crime and violence.

Amer-I-Can, a program funded by Football Hall of Fame member Jim Brown, is well known for its gang outreach work in the Los Angeles County jails.
