OAKLAND, Calif. --Oakland police have made a small number of arrests for disobedience and vandalism in a downtown protest this morning following the election of Republican candidate Donald Trump as U.S. president, officers said.
Police helicopters are set to patrol the area by 2:30 a.m. An officer at the patrol desk said shortly before 2 a.m. that the department will "hopefully put a stop to it soon."
Following the election of Trump, at least 50 protesters marched from downtown to state Highway 24, where a protester was hit by a car near the Claremont Avenue off-ramp. The victim is being treated for serious injuries, according to the CHP.
