An “Antifa” protest erupted into violent chaos in Berkeley, California, on Sunday — forcing police to unleash a smoke grenade and arrest at least 10 people, according to reports.

More than 100 protesters dressed in black pushed past police barricades in a downtown city park and assaulted at least three people by punching and kicking them. One of the victims was a right-wing male demonstrator.

Police broke up the violent outburst by launching what appeared to be a smoke grenade and arrested demonstrators for fighting and violating a no-mask rule, according to the LA Times.

They also fired a rubber bullet at a demonstrator who tried to cross a barricade into Martin Luther King Park.

Wild video footage also shows the moment officers tackled one man and cuffed another at Civic Center Park as the crowd swelled, according to NBC.

“Let him go!” one protester is heard screaming while others shoot cellphone footage of the arrest.

“Move back!” a police officer shouts at protesters.

At least one of the people detained had violated the no-mask rule, according to local station KCRA.

Two men were arrested for fighting, the station reported. A woman was busted for wearing a bandanna over her face and refusing to remove it.

The “Rally Against Hate” drew thousands of people to city parks, along with the Berkeley college campus, on Sunday afternoon.
