OAKLAND (CBS SF) – Police arrested at least nine suspects while serving warrants throughout the Bay Area Friday morning as part of a multi-agency operation targeting suspects thought to be responsible for violent gang activities like homicides, shootings and robberies in Oakland.

Oakland Police spokeswoman Johnna Watson declined to name the other agencies involved.

A statement published around 6 a.m. indicates the department is working closely with the Alameda County District Attorney’s Office.

Around 9:30 a.m., Watson said in an email that “the operation continues,” and more information will be provided toward its conclusion.
