LOS ANGELES (AP) - The FBI says more than 500 law enforcement officers from a task force served arrest warrants in a 30-month investigation targeting members of at South Los Angeles street gang
The agency says 23 members of the Rollin' 30s Harlem Crips who were charged in federal indictments were taken into custody Thursday.
Officials say the gang operates in South LA and has ties to other gangs. Police say the indictments charge them for their roles in a drug distribution network.
Police say the investigation by federal and local law enforcement known as "Operation Thumbs Down" was initiated in 2011 to target the violent gang. The investigation's name is a reference to the hand gestures used by the gang - two thumbs pointing upward to represent the "H'' in the word "Harlem."
