In the San Francisco Bay Area, protesters demonstrating against the Michael Brown and Eric Garner grand jury decisions clashed with police officers late Sunday night.
In Oakland, protesters attempted to block a highway, the Los Angeles Times reports, and when California Highway Patrol officers tried to get them back to the street, an explosive was thrown and two patrol cars vandalized. The officers used tear gas; one arrest was made.
Earlier in the evening, 500 to 600 people marched from the UC Berkeley campus to downtown, and some demonstrators smashed the window of a Radio Shack. Berkeley Police said that when a man tried to stop them, he was hit with a hammer.
