U.S. Capitol Police officers arrested Olson on Tuesday, November 5, 2024, at the U.S. Capitol Visitor Center. At about 12:30 p.m., Olson entered the complex and was asked to remove his belongings for inspection in a security x-ray machine. When Olson’s black coat passed through the x-ray machine, an officer saw what appeared to be a torch and a small firearm. The officer recovered a small torch device and an orange flare gun from the coat. Officers also noted that Olson’s small backpack reeked strongly of gasoline. Inside the backpack, officers found two bottles filled with fuel.

According to the USCP officer, Olson stated he was at the Capitol to send a message to Congress and that he had brought the torch and flare gun to “light up the message in fire.” Another officer asked Olson what message he was planning to deliver. Olson removed a red closed envelope from under his shirt and stated it contained the message he wanted to send to the members of Congress. USCP officers handcuffed Olson and patted him down for additional contraband. Olson refused to provide identification.
