This is a breaking story and will be updated.

A group of Concord High School students left school and marched downtown chanting “No More Ice” Thursday. The video was posted on Sebastian Fuentes Facebook page.

Students began walking out at around 12:30 p.m. Between 150 and 200 students left to walk downtown near the State House. They chanted and waved to passing cars; some drivers honked their horn in support, drawing cheers from the students.

Sebastian Fuentes was working at the Democratic Party headquarters in Concord a few blocks away when he saw the students on the way to get his lunch.

He videotaped the group, but didn’t converse with the students.

“I was just a bystander. It was a powerful moment seeing our youth in the neighborhood expressing themselves,” Fuentes said. An immigrant from Peru, he moved here when he was 21 and is now a U.S. citizen.

It was a student event, not a school sanctioned event, according to one of the assistant principals Kaileen Chilauskas.

“They made the choice to leave school,” Chilauskas said. Some may have been able to leave because it was the end of their day, she said.

She said the students who left will be spoken to. If there would be any discipline it would be on an individual basis, she said.

The administration messaged parents the night before:

“We understand that some students are coordinating this demonstration in response to recent events in Minneapolis involving Immigration and Customs Enforcement.

We want to clarify that this demonstration is not sponsored or sanctioned by Concord High School or the Concord School District. It has been organized independently by students through social media outside of school.

Our expectation is that students remain in their scheduled classes for the full school day. If a walkout does occur, the administrative team, in coordination with the Concord Police Department, will be present to ensure that students are safe and that any assembly remains peaceful. Participation in any such demonstration is solely the choice of individual students; no student is being directed or compelled to take part in it.”
