Hundreds of people have held protests against presumptive Republican presidential candidate Donald Trump in Fresno, California.
The demonstrations on Friday followed similar anti-Trump rallies in other US cities that resulted in violence and arrests.
Some of the protesters held signs supporting Democratic presidential hopeful Bernie Sanders or waved Mexican flags, while others walked down the street, chanting "Whose streets? Our streets!" or "Trump needs to be dumped."
Police rushed to break up a tussle that broke out between protesters and Trump’s supporters, but nobody was arrested.
Inside the arena, some protesters shouted anti-Trump slogans which led to the business mogul asking police to "get them out."
During his speech, Trump said he would “make a strong play” in California, adding “I am going to make a heavy, heavy, heavy play because I honestly think with getting these massive crowds … we are going to win California."
He also lambasted US policy in the Middle East, saying, “We got death, we got destruction, we got ISIS (Daesh).”
Friday rallies came after another anti-Trump protest in New Mexico turned violent on Tuesday night when protesters lit fires, smashed a door and threw rocks outside Albuquerque's convention center.
The protesters broke a glass door to the convention center and some of them taunted police and jumped on police vehicles.
Police managed to keep the protesters and Trump's supporters apart unlike a similar incident in Chicago where violence erupted between his supporters and protesters in March.
Trump has secured the required number of delegates to win the GOP nomination, according to the latest AP count.
His total count of delegates reached 1,238 after a small number of unbound party delegates told the AP that they would support him.
Trump was the only remaining Republican candidate in the race after his last two opponents Senator Ted Cruz of Texas and Ohio Governor John Kasich dropped out of the race earlier this month.
