Denver police on Sunday morning confirmed authorities arrested 12 people during follow-up demonstrations Saturday, after tens of thousands flooded downtown streets for the “No Kings” afternoon protests.

Some charges include assault to a peace officer and aggravated assault, according to a Denver Police Department spokesperson, who confirmed arrests with The Denver Gazette on Sunday morning.

The first incident reported happened at around 3:30 p.m., when many “No Kings” protesters left the downtown area after a peaceful protest, according to the police.

Lincoln Street remained closed at 14th Avenue and Colfax. Broadway and 14th Avenue, including other roads near the Capitol, were reopened at the time. The “No Kings” protest was scheduled until 4 p.m.

At one point, police arrested a man for possessing a knife, the police spokesperson said.

At around 3:50 p.m., a small group of protesters marched to 20th and Chestnut streets. Officers there made multiple loudspeaker announcements to deny highway access, according to police.

At roughly 4:05 p.m. officers declared the gathering an unlawful assembly and continued to warn of chemical munitions use. Then, 10 minutes later, officers deployed smoke and pepper balls, police said.

Police made “several” arrests during that time, according to authorities.

At around 6:45 p.m., a group of protesters marched west on 6th Avenue through eastbound traffic, before stopping at 6th Avenue and Santa Fe Drive, according to the DPD spokesperson.

The spokesperson said police staged at the intersection, shouting loudspeaker announcements that the gathering was an unlawful assembly and to prevent protesters from reaching the 6th Avenue freeway.

“After allowing time for the group to disperse, officers deployed smoke and officers dispersed the group,” the DPD spokesperson said.

The spokesperson added no pepper balls were used in that incident.

“Following this incident, the size of the group of protestors diminished as they moved eastbound and back to the State Capitol,” the spokesperson said.

Denver police didn’t report any further incidents

Police said authorities arrested 12 individuals for alleged aggravated assault, assault to a peace officer, graffiti and other municipal offenses.

Saturday’s Denver protest was one of over 50 “No Kings” demonstrations scheduled across Colorado. Not to mention one of hundreds taking place across the country on Saturday.

ing, the processing of arrestees remains ongoing.
