The Countywide Gang Task Force was established in August 2005 by mutual agreement between the membership of the San Mateo County Police Chiefs and Sheriffs’ Association.

Their mission is to take a pro-active approach to the increased presence of gang activity and related violence in San Mateo County through intelligence driven enforcement operations in order to improve the safety and quality of life in our community.

Cargo Theft Task Force

The San Mateo County Cargo Theft Task Force (AIRCATS) was created by several cooperating law enforcement agencies in response to the increasing number of thefts being reported of cargo-in-transit, particularly high tech goods and computer components. AIRCATS is staffed by investigators from the San Francisco Police Department's Airport Bureau, the San Mateo County Sheriff's Office, and the Federal Bureau of Investigation.

AIRCATS's objective is to detect, arrest, and prosecute those persons  who commit such thefts and to prevent, interfere with, and disrupt the unlawful traffic in stolen cargo. To reach this goal, AIRCATS relies on cooperative relationships with freight brokers and freight forwarders operating to and from the San Francisco International Airport. AIRCATS works closely with other regional law enforcement task forces also engaged in abating the theft of both high tech and other cargo.
