NEW LEBANON, Pa. (WKBN) – Federal agents have arrested a Mercer County woman they believe took part in the riot on the U.S. Capitol.

Rachel Powell, 40, was arrested in New Castle Thursday.

She is charged with obstruction, depredation of government property, restricted building or grounds with a dangerous weapon, restricted building or grounds, and violent entry or disorderly conduct.

An FBI agent’s affidavit on a warrant issued Wednesday said that after a group inside a Capitol room stated they needed a plan, Powell told them they should coordinate together. Her lawyer argues she’s not a flight risk.

She appeared in federal court Friday in Pittsburgh where she entered no plea. She remains detained in the Butler County Jail until her next scheduled hearing on Feb. 9.

Investigators were at her New Lebanon home Thursday. They did not confirm what they were looking for and only said they were “conducting court-authorized law enforcement activity at that location.”

Powell is believed to be the woman known as the “Bullhorn Lady” in images released by the Department of Justice of people of interest in the riot.

According to New Yorker magazine, Powell confirmed to the publication that she is the woman in the photos.

The criminal complaint filed in U.S. District Court states that investigators were able to identify Powell as the woman pictured using a bullhorn, instructing people how to gain entry into the Capitol. Investigators said she can be heard saying the rioters should “coordinate together if you are going to take this building.” The court documents also allege that she instructed the group to break another window.

Pictures show Powell using a large pipe as a ramming device to breach windows of the Capitol, before crawling inside, according to the criminal complaint.

Investigators say they were able to identify Powell by her Facebook page in which she is seen with the same earmuffs that she carried on January 6.

Investigators also cited the article in the New Yorker as evidence, as well as cell phone data that showed she was in Washington, D.C.

Powell has eight children and previously lived in California before moving to the area.
