Anti-ICE protesters pulled down a star-spangled banner that hung over a federal building holding illegal immigrants on July 12, and flew a Mexican flag in its place.
The protest at the Immigration and Customs Enforcement (ICE) facility near Denver, Colorado was organized by a collection of local socialist, Marxist, and communist organizations, along with other groups opposed to current U.S. border policy.
They were calling for the shutdown of “concentration camp” detention centers and to “let them all in.”
Denver is one of 10 cities nationwide where raids by ICE officials targeting criminals are expected to start on July 14.
Photographs and videos posted to social media show the flags being changed as a crowd of hundreds looked on outside the facility in the city of Aurora, which forms part of the Denver metro area.
Police later restored the U.S flag to its position.
Aurora police chief Nick Metz praised the Aurora police and community for the way the demonstration went.
“Thank you to everyone who remained peaceful & took the time to thank my cops,” he wrote on Twitter. “Thank you to all the officers who were there to ensure everyone’s safety.”
The protest, which was dubbed the March to Close Concentration Camps, called for the closure of detention centers and for all those being held to be granted entry to the United States under the strapline “Let Them All In.”
“It starts on Sunday, and they’re going to take people out and they’re going to bring them back to their countries. Or they’re going to take criminals out, put them in prison, or put in them in prison in the countries they came from. We’re focused on criminals as much as we can before we do anything else.”
