AURORA, Colo. — The Aurora Police Department has released pictures of people who were possibly involved in the removal and vandalizing of an American flag at an ICE detention facility Friday.

On Tuesday afternoon, APD published four photographs of persons of interest in the case.

According to the Associated Press, protesters pulled down the American flag in front of the detention center, tried to burn it and replaced it with a Mexican flag.

Friday night’s protest, one of many coordinated across the country, drew about 2,000 people and was mostly peaceful.
