The Sheriff's Department called for all available units -- with riot gear -- to assist in redirecting traffic and blocking protesters.
As a sheriff's patrol unit shut down the intersection to prevent vehicles from running into the protesters, a motorcyclist crashed into a sheriff's car, but no one was injured, according to the Sheriff's Department.
The group was protesting layoffs and working conditions at area warehouses.
They are also seeking full- rather than part-time temporary jobs, a living wage, health insurance and the right to unionize.
The group, called /*Warehouse Workers United*/, had made similar demands weeks earlier, and when they went unheeded, they said they would conduct an act of civil disobedience, which occurred today when they parked a forklift in the intersection and refused to get out for the street.
After negotiating with law enforcement, planned arrests were made on about seven young protesters, and the forklift was pushed out of the way by a patrol car.
