A U.S. Immigration and Customs Enforcement facility in Colorado was the site of protests on Friday where activists removed an American flag that flew on the outside of the government building.

Hundreds of protesters had assembled at the Aurora facility, which houses unauthorized immigrants, to protest the impending ICE raids that are reported to begin on Sunday. Protesters raised the national flag of Mexico in place of the American flag and vandalized a Blue Lives Matter flag, which honors law enforcement, by spray painting the words "Abolish I.C.E." on the banner and flying it upside down alongside the Mexican flag. Local authorities worked quickly to take down the symbols of protest and restore the American flag.

The protest in Colorado was one of several that occurred across the country on Friday as part of the #LightsForLiberty-organized "March to Close Concentration Camps" which called for the closure of all immigrant detention centers in the U.S. and for the immigrants being held to be granted access into the country. Protests were also held in California, New York, and Oregon.

ICE raids are expected this weekend in several U.S. cities including New York City, Los Angeles, Miami, Chicago, Baltimore, Atlanta, Houston, and San Francisco.

Law enforcement in Aurora said that the protesters largely remained peaceful on Friday evening, even thanking some of the police officers for their work.
