Police in riot gear were called in to separate Donald Trump protesters and supporters Friday afternoon after they clashed outside a rally for the presumptive Republican nominee in San Diego, California.
At least three people were arrested, according to San Diego Police.
The roughly 1,000 demonstrators were gathered on both sides of the street outside the San Diego Convention Center.
Some protesters holding Mexican flags and flags from other countries yelled, "Dump Donald Trump."
Trump supporters chanted, "You can't vote," and, "Build that wall!"
A helicopter loudspeaker and ground loudspeakers repeatedly made announcements that unlawful assembly was declared, and anyone in the area would be arrested if they stayed.
