Santa Clara County inmates are set to refuse food to protest what they call the arbitrary use of solitary confinement and other jail conditions.

A sweeping take-down by federal and local law enforcement resulted in an indictment against two-dozen suspected Nuestra Familia leaders.

Dozens of alleged Nuestra Familia gang members were indicted by a criminal grand jury on 77 charges, which range from meth sales to murder. It’s the largest gang case Santa Clara County has ever tackled: 48 people charged in a hefty 99-page indictment. “This is a sophisticated, complex criminal organization that required a sophisticated, multi-faceted law enforcement and prosecutorial response,” District Attorney Jeff Rosen said in a statement released Tuesday morning.
