The sheriff's office arrested 78 people. Of those, just 19 live in Oakland. Twenty-eight others live elsewhere in the Bay Area.
Nineteen are from other areas of California. There were 12 out-of-state people arrested.
"Well I don't have any indication; in other words they haven't told me why they're here, but you do have to question why somebody's here from out of state in the middle of Oakland at night causing trouble," sheriff's spokesperson J.D. Nelson said.
Of the 78 arrested, 60 are men. Sixty-six people are being released today on misdemeanor charges. The other 12 are being kept and charged with felonies.
