Several demonstrators taking part in the A Day Without a Woman marches to commemorate International Women’s Day were arrested outside of Trump International Hotel at Columbus Circle in New York.

Staging a sit-down protest, NYPD officers detained several protestors after they warned them that they were blocking traffic. When they did not cooperate, cops put them in zip ties and herded them into the back of an NYPD van.

Women’s March, through PR firm Sunshine Sachs, confirmed to Deadline that 13 organizers and supporters of the Women’s March were arrested today by the New York City Police Department in an act of civil disobedience outside Trump International Hotel and Towers in Columbus Circle.

“Today, the national leaders of the Women’s March gathered with allies and those participating in the day’s actions for a show of solidarity and revolutionary love. After a peaceful protest in New York City in honor of A Day Without a Woman, 13 organizers were arrested by the New York City Police Department in an act of civil disobedience outside of Trump International Hotel & Towers. This is a developing story and additional information will be forthcoming,” read the updated statement.

Through all this, Women’s March documented their experience via their Twitter page, posting videos and pictures as the day went on – even after they were detained by officers.

“We are blocking traffic as a form of civil disobedience in Columbus Circle (outside Trump Hotel),” a tweet from the organizers stated. Soon after they were detained, they shared the following pictures with the message: “Some of us have been arrested. We are not sure what precinct we are being taken to at the moment. But we are together, reSisters.”

“Many of our national organizers have been arrested in an act of civil disobedience. We will not be silent,” a Women’s March’s tweet stated.
