A major joint operation and drug bust was underway in the Antelope Valley Tuesday.
The LA County Sheriff's Department, with the DEA, U.S. Army and others, is raiding hundreds of illegal marijuana grows that officials say are related to Mexican cartels.
Bulldozers are being put to work at several locations in the Antelope Valley, to destroy one of the largest illegal marijuana grows in LA County history.
It contains more than 70 individual green-houses.
Villanueva says, from this grow alone, they plan to serve up to 200 search warrants.
One precious commodity that the marijuana cartels are using, the sheriff says, is water, which is in short supply in the high desert.
Villanueva says California has legal marijuana grows that are small in size and are tightly regulated but they're being put out of business by the illegal operations.
Villanueva says it's the largest operation ever in the department's history.
