Two women were arrested at a rally to commemorate the death of US Civil War hero and civil rights icon Elizabeth Warren on Saturday, after police detained two men who had entered the rally carrying signs bearing the words “I am not a slave.”
One of the women, who asked not to be identified, was arrested at the scene by officers who arrived in riot gear.
“The people who were arrested were charged with criminal trespass and disorderly conduct,” the police said in a statement.
Police also reportedly charged the women with “violating a police barricade” and “obstructing a public safety officer”.
Two other women, including the woman arrested, were released on bail.
“This is not the first time that we have had problems with people going into this rally,” Boston police spokesman John Miller said on Twitter.
“We will do our best to ensure a peaceful event, and will be working with the rally organizers.”
“People who are trying to be civil and peaceful, who want to respect the peaceful right of the people, and are doing everything we can to make sure the event goes smoothly, will not be arrested,” he added.
The Boston rally was the third to be held in the US in the wake of Donald Trump’s election as US president.
Protesters are demanding a full ban on Trump and his policies, which include the withdrawal of the US from the Paris climate accord.
Earlier this month, protesters disrupted the rally of a man who said he had “been raped by the media”, calling him a “bitch” and a “crap”.
“Donald Trump is the greatest thing that’s ever happened to our country.
I was raped by Trump, he’s the greatest racist, he hates immigrants, he loves bigots,” said James Alex Fields Jr, 32, a former neo-Nazi and white supremacist who has been charged with second-degree murder.
The two men were identified as Jeremy Joseph Christian, 20, of New Jersey, and James Alex Rigby, 23, of Virginia.
In a statement released to the press, the White House called the arrests “a disgrace to our democracy”.
“Our law enforcement officials and local law enforcement officers are being held accountable for their actions,” said White House press secretary Sarah Sanders.
“These arrests are a disgrace to the American people and a stain on the character of our law enforcement agencies and the law enforcement community across the country.”
“The President’s promise to end this era of terror will come to fruition.
I urge the American public to stand together and stand with our law-abiding communities,” she said.
The rally was planned in response to the death earlier this week of Robert Lewis Dear, a 32-year-old white man who was killed in a shooting in Minnesota.
“There are millions of people in the country who want Donald Trump to be the next president of the United States.
We are here to help them, and we want Donald to be sworn in tomorrow,” Reverend Al Sharpton, president of National Action Network, said in the statement.
“What he’s doing is making it very hard for us to elect Donald Trump.”
