Nearly 400 people are under arrest following Operation Allied Shield IV (OAS). The multi-agency operation was conducted on Friday, July 19th through Saturday, July 20th. This proactive approach to law enforcement is the only operation of its kind in the United States. Operation Allied Shield is a regional approach to border security and crime fighting. OAS targeted San Diego gangs known to support drug smuggling, human trafficking and other illegal cross-border crimes.

Illegal drugs with an estimated street value of $455,000, weapons and more than $5,000 in cash were also seized.

During the operation; more than 1,000 deputies, officers, federal and state agents conducted parole and probation checks, traffic stops, as well as served search and arrest warrants to locate prolific gang offenders and take them off the streets of San Diego County.

Funding for Operation Allied Shield IV came from a 2012 $5.5 million grant from the Department of Homeland Security under Operation Stone Garden. The full resources of the grant will also be used for other operations.

Gang crimes threaten where we live, play and our schools. The message for gang members is this: the Sheriff's Department will not tolerate criminal activity. We will continue to work with our federal, state and local partners to disrupt, dismantle and destroy the gangs and we won't stop until the work is done.
