City officials say they have secured a $5 million civil judgment against a Los Angeles street gang and 11 members who control the heroin trade in the downtown area.

City Attorney Rocky Delgadillo and other law enforcement officials announced the judgment against the 5th & Hill gang on Tuesday. Officials say it's the first obtained against a gang in California.

The judgment stems from a permanent injunction that restricts gang members from committing crimes and being a nuisance. A state law allows cities to collect financial damages for harm that gangs cause communities.

City officials say the gang is known to have a monopoly on heroin sales in downtown Los Angeles.
