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 control the 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 scuffling 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 were involved in the protest, but television footage showed a large crowd.

Some protesters surrounded a police car, smashed its windows and stomped 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 in protest against the Republican candidate.

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

One of the central pillars 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.
