Crowds gathered outside the OC Fair & Event, Orange County, California clashed with thousands of supporters of US presidential candidate Trump. Police were called in to prevent riots, however, some scuffles still occurred, CNN reported today.

Police arrested 20 people after protesters tried to block an intersection. Trump supporters were punched in the face after scuffles broke out with people accusing Trump of racism.

Lt. Mark Stichter, information officer for the Orange County Sheriff's Office, said it was impossible to estimate how many people participated in the protest, but television images showed a large crowd.

Some protesters surrounded a police car, smashed its windows and trampled on it. Police were forced to create a perimeter around it and asked the crowd to disperse. Protesters said they were against Mr. Trump’s rhetoric, which was interpreted as anti-immigrant. Some carried Mexican flags to protest the Republican candidate.

"I oppose Trump's nationalist agenda, which divides people," said Rojelio Banuelos, a 26-year-old student.Banuelos, female studentKatie Brazer says protesters are fed up with Mr Trump's hateful messages.

One of the central themes of Trump's campaign was his plan to build a wall along the US-Mexico border to stop illegal immigration, crime and drug trafficking. Trump insisted that Mexico would pay all the costs.
