The Las Vegas Valley has more than 300 gangs and 20,000 gang members, the Las Vegas Sun reported.
Local gang members average from 14 to 21 years old, with recruitment typically starting in middle school, Metro Police said.
Many of the city?s more established gangs are subsets of larger, California-based organizations. But there also are ?hybrid gangs,? more loosely organized groups that are harder for police to contain.
Hybrid gangs, which are barely organized and more violent, make it harder for police to contain them.
The Metro Police have seen a large increase in gang activity, during the past decade,according to the Las Vegas Sun.
Known gangs in Las Vegas include, Bloods and Crips, the Rolling 60s, The Playboy Bloods, The West Side Piru Bloods and The Norteņos.
