The female protester who was seen being punched in the face by a white supremacist during a pro-Trump rally has spoken out.

Louise Rosealma was filmed getting sucker-punched by Nathan Damigo, the founder of a white supremacist group, after violence broke out on Saturday between groups of Trump supporters and detractors holding rallies in downtown Berkeley.

Thankfully, Rosealma - who was knocked to the ground by the force of the punch - was not seriously injured and suffered only cuts and bruises in the attack.

However, the abuse didn't end there as she says she has since been targeted online by alt-right trolls after the footage went viral.

'They are trying to make me into this trophy – the victory of the alt right and neo-Nazis,' she told CBS. 'It's petty and pathetic.'

She said that the harassment had been 'non-stop' on every single social media platform since the video emerged online.

'They just are trying to get to me,' she added.

The City of Berkeley confirmed that authorities are reviewing video footage of the protests and would be looking to prosecute anyone seen committing an act of violence.

Rosealma had traveled to Berkeley from Southern California with her boyfriend and friends as part of the Antifa anti-fascist group to take part in the counter demonstration to the Patriot's Day event organized by alt right.

'We went to show our support and be bodies present in counter protest,' she told CBS.

But Rosealma and her group were barely in the park before they were rushed by a group of counter demonstrators.

'Things got very intense, very quickly,' she said. 'A smoke bomb went off in the area where the white nationalists and neo-Nazis were… Everyone was confused.

'They started rushing and started attacking people.'

Rosealma said she lost her friends and boyfriend in the chaos and was trying to escape when she encountered Damigo.

'I remember is turning around and from the corner of my eye I saw this fist coming at me,' she said. 'I put my arms up to try and push him away as much as I could. He just threw himself into me.'

Rosealma said the punch to her nose, which left her with a cut and bruises, knocked her down and by the time she had got back to her feet, her attacker had fled. The assault was completely unprovoked, she said.

But the violence didn't end there.

'I was punched twice more by two other people,' she said, 'People kept trying to throw me down to hit my head on the rocks that were in the planter. I was just trying to not get my skull cracked open.'

Eventually, the 'terrified' Rosealma was able to escape the crowd and find her boyfriend who she says was covered in blood. During the entire incident, she says she never spotted any Berkeley police officers.

However a deleted post, purportedly written by Rosealma, 20, a photographer, on Facebook ahead of the protests, stated that she was 'heading to Berkeley to disrupt the white supremacist/neo-nazi circle jerk today.

'Nervous af but determined to bring back 100 Nazi Scalps today.'

At least 21 people were arrested after a pro-Trump 'Patriots Day' rally clashed with counter-protesters at Berkeley's Martin Luther King Jr Civic Center Park on Saturday.

Hundreds of people with opposing opinions on President Donald Trump threw stones, lit fires, tossed explosives and tear gas and attacked each other with makeshift weapons as police stood by.

About 250 police officers were deployed to try and quell the violence, as Berkeley officials turned to Oakland Police Department for backup, according to the Los Angeles Times.

The rally was organized by the Liberty Revival Alliance in response to the hundreds of Tax Marches being held in cities across the country - demanding Trump finally release his taxes.

This is the third time that violent confrontations have broken out on the city's streets in recent months.

But Saturday's brawl was by far the worst violence the city has seen to date.

Berkeley Mayor Jessie Arreguin said: 'It's challenging. They had helmets. They had shields, they had weapons and this is something we really haven't seen before.'

Damigo, who claims he is a former Marine, has not responded to requests for comment on the video.

But he later posted a different clip on Twitter showing specks on blood down his arm and shirt which he claimed he received while he was 'administering first aid' to someone.

Damigo, a former Marine corporal and the founder of a white supremacist organization Identity Evropa, has previously served two years in jail for armed robbery after he confessed he 'flipped out on a guy,' the Bee reported.

A former leader of the now defunct, National Youth Front, Damigo is also a huge supporter of Donald Trump.

During the week of Trump's election, Damigo posted a video where he fantasized about a 'Calexit' the proposed secession of California, named after the UK's Brexit.

'The remaining few of us who are white would white-flight ourselves out of here and join you guys in the rest of the country, and we could do our own thing and California could just pretty much devolve into cannibalism,' he said.

'The state has just radically changed,' said Damigo, who grew up in Silicon Valley and attended a private Baptist school. 'If you're white and you live here, it's like being in a foreign country.'

Last year, Stanislaus State students complained that the 30-year-old, who was majoring in social studies at the school, was attempting to build 'one of the fastest growing white supremacist groups in the U.S.'

When students demanded he should be expelled, Stanislaus President Ellen Junn posted a statement on the university website saying that 'Stanislaus State and the CSU have an obligation and commitment to the founding principles of our American democracy – a democracy that upholds the First Amendment's protection of freedom of speech, even when that speech may be controversial or offensive to others.'

However, there have been renewed calls for his expulsion this weekend after the video of him assaulting the woman went viral.

DailyMail.com has reached out to Damigo for comment.

While it does not appear that Damigo was arrested at the rally, more than 20 other protesters were taken into custody as a riot broke out.

Some of those arrests were on suspicion of a deadly weapon, according to Officer Byron White of the Berkeley Police Department and the LA Times.

Both sides threw explosives and sprayed tear gas at each other, and a number of people had to have milk poured into their eyes after being affected by the gas.

Dozens of people were pictured bloodied or otherwise injured as fights continued to break out in the California city.

Both groups threw rocks and sticks at each other, and even used a large trash bin as a battering ram, according to the LA Times. A bank even boarded up its ATMs before the rally as a precaution.

Berkeley Police Department spokesperson Officer Byron White told Buzzfeed News: 'The City of Berkeley police department is a small to medium-size department. Our police department total is 176. I can tell you most of that 176 is here today.'

He also said city officials did not receive protest permit requests from either group, but found out about them through social media and distributed flyers.

White also explained that because there was no official communication between the city and protesters, officers had to estimate how many demonstrators would show up.

He said: 'The amount of people at the park for the demonstration was in the hundreds.

'It's a challenge for us to keep that amount of demonstrators inside that area with the amount of people we had. It would require another level of force for us to do that.'

However, he explained that he does not think they underestimated the protests, saying: 'Every time we have a demonstration in the city of Berkeley, we learn a little bit from it'.

During the protests Berkeley police posted to Twitter a picture of some of the makeshift weapons they had already confiscated, including metal pipes and baseball bats.

Canadian alt-right blogger Lauren Southern spoke at the event and criticized societal change and Kim Kardashian, the Los Angeles Times reported.

Demonstrators later left the park and proceeded to walk along Berkeley streets while police followed closely.

A weekly farmer's market held in the park was cancelled due to the planned demonstration.

But one vendor came to sell her wares anyway and told the LA Times: 'Rain or shine or fascism we will be here.'

The rally follows a March 4 confrontation planned by several of the same groups that left several people injured and led to arrests.

In February, protesters threw rocks, broke windows and set fires outside the UC Berkeley's student union building, where then-Breitbart News editor and provocateur Milo Yiannopoulos was set to speak.

His presentation was cancelled.
