MADISON — A Wisconsin man who allegedly assaulted law enforcement officers with pepper spray during the breach of the U.S. Capitol on Jan. 6, 2021, was arrested Wednesday, March 16, in Ashland.

Riley D. Kasper, 23, of Pulaski, Wisconsin, is charged in a criminal complaint filed in the District of Columbia with assaulting, resisting or impeding officers with a deadly or dangerous weapon to inflict bodily injury, civil disorder, engaging in physical violence in a restricted building or grounds and related offenses. He appeared in federal court in Madison on Thursday, March 17, before Magistrate Judge Stephen Crocker, according to the United States Attorney's Office for the Western District of Wisconsin.

Kasper, who was represented by Federal Defender Joseph Bugni, will be released from custody on a GPS monitor. Conditions of his release include no travel outside of the continental U.S.; no firearms, destructive devices or other weapons; and he must stay away from the District of Columbia unless for court. His initial appearance in federal court in the District of Columbia was set for Tuesday, March 22 via Zoom.

Kasper is accused of being among the crowd that breached the Capitol and disrupted a joint session of Congress that was in the process of ascertaining and counting the electoral votes related to the presidential election.

According to court documents, on Jan. 6, starting at approximately 1:50 p.m., Kasper sprayed an aerosol canister of what is believed to be pepper spray towards law enforcement officers attempting to secure the Capitol building and grounds. That day, Kasper also communicated on social media with another individual, declaring, among other things, “I pepper sprayed 3 cops so bad they got undressed and went home,” and “As you can see in that video, it was my group that busted the first gate and kept chasing the cops down and pushing them back at the capitol.”


The next day, Kasper communicated with another individual on social media, saying, “You charge that line and start spraying they start running for cover like you’re coming at them with an ak” and “there is definitely something satisfying about pepper spraying cops in riot gear …”

The case is being prosecuted by the U.S. Attorney’s Office for the District of Columbia and the Department of Justice National Security Division’s Counterterrorism Section. Valuable assistance was provided by the U.S. Attorney’s Office for the Western District of Wisconsin.

Pulaski is located in east-central Wisconsin. The village straddles Brown, Oconto and Shawano counties and has a population of 3,870 according to the 2020 census.

The case is being investigated by the FBI’s Milwaukee and Washington field offices. Assistance was provided by the Metropolitan Police Department and the U.S. Capitol Police.

In the 14 months since Jan. 6, 2021, more than 775 individuals have been arrested in nearly all 50 states for crimes related to the breach of the U.S. Capitol, including over 245 individuals charged with assaulting or impeding law enforcement.
