Federal authorities alleges Karol Chwiesiuk and his sister Agnieszka Chwiesiuk breached the U.S. Capitol during the Jan. 6 riot. (U.S. District Court)

The sister of a Chicago police officer who was previously charged in connection to the Jan. 6 insurrection at the U.S. Capitol is now facing criminal charges herself after she too allegedly illegally entered the Capitol.

Agnieszka Chwiesiuk has been arrested after federal investigators identified her in photos and videos from inside the Capitol building during the riot. She was charged with entering and remaining in a restricted building or grounds; disorderly and disruptive conduct in a restricted building or grounds; disorderly conduct in a Capitol building; and parading, demonstrating, or picketing in a Capitol building.

According to the feds, she can be seen alongside her brother, Karol Chwiesiuk, a CPD officer who is facing five misdemeanor charges stemming from his own alleged involvement in the riot.

According to a statement of facts from the FBI, Agnieszka Chwiesiuk attended a rally held by former President Donald Trump on Jan. 6 before walking with her brother and others down Pennsylvania Avenue toward the Capitol.

“Agnieszka was among the rioters in the NW Plaza, and at approximately 2:58 p.m., she had made her way to the front of the crowd and entered the Capitol through the broken-out doorway of the Senate Wing Door,” an FBI agent wrote in the document.

From there, she allegedly entered the Capitol’s Crypt, then walked toward a Senate wing door before exiting the building through a broken-out window after less than 10 minutes.

Investigators allegedly identified Agnieszka Chwiesiuk in open source videos, surveillance footage from the Capitol and pictures recovered from her brother’s phone showing her inside the Capitol.

After Karol Chwiesiuk was identified and arrested at his Chicago home in June 2021, Agnieszka Chwiesiuk — who was also present — asked if she too was going to be arrested, according to the FBI.

“At that time, the agents responded that they were not there to arrest her,” the FBI agent wrote in the document.

Karol Chwiesiuk is already facing charges including disorderly conduct, disrupting government business and entering a restricted building, according to a federal complaint.

Geolocation data recovered by investigators shows he traveled from Chicago to Washington, D.C. on Jan. 4 and was present there on Jan. 5-6 before returning to Chicago on Jan. 8, the complaint states.

In text messages to a friend on Jan. 3, Karol Chwiesiuk said he planned to go to Washington, D.C. to “save the nation,” adding that he planned to “f--k up some commies,” according to the complaint. 

He is scheduled to go to trial next year.
