The Post Millennial has obtained the identities of the violent leftist agitators who were arrested outside of Seattle City Hall on Tuesday while attempting to disrupt a pro-Christian rally. Seattle Police apprehended eight individuals on various criminal charges, including felony assault on a police officer. The defendants include trans activists, a public school teacher, and individuals who have documented involvement with the anarchist extremist group, Antifa.
Of the eight people arrested, seven were booked into jail. Their ages range from 19 to 60 years old, and half of the accused live outside of city limits, according to police records obtained by The Post Millennial.
Seattle Police apprehended the following individuals:
Micah Thomas Napier, 23, of Seattle, Washington - Case Number: 2025-143827
Napier was arrested and booked into King County Jail on third-degree assault charges. He was released from custody the following day, jail records show.
According to a probable cause affidavit, Napier refused to comply with several police demands and allegedly engaged in an "attempted theft." When an officer responded to the situation, Napier allegedly kicked the officer "with a straight forward kick," and was placed under arrest, per the affidavit.

Napier, who uses the alias "Moses," is a documented Antifa militant who was previously arrested during a violent Antifa direct action in the former deadly CHAZ zone on election night in November 2024. He uses "they/them" pronouns and is heavily involved in Seattle's punk rock scene, according to his social media accounts.
The Post Millennial captured Napier's Tuesday night arrest on video, which showed a brief commotion before Napier was handcuffed and taken into custody. Napier had been wearing a blue bike helmet, a surgical mask, a black and grey top, and cargo pants at the time of his arrest. His blue-colored could be seen poking out of his helmet, according to screenshots taken from the video.
While the affidavit only mentions the suspect as a "John Doe," The Post Millennial was able to determine that the unnamed suspect mentioned in the report was Micah Napier via the timestamp of his arrest listed on jail bookings, which match the timestamp on the affidavit.

Seattle Police arrested eight leftist agitators who mobilized to disrupt a pro-Christian rally at Seattle City Hall on Tuesday, following a weekend of political unrest at the hands of anarchists and trans activists. The event came in response to Democratic Mayor Bruce Harrell condemning a Christian worship event on Saturday, which was held in the former deadly CHAZ zone in the Capitol Hill neighborhood of Seattle. Antifa militants and trans activists mobilized to disrupt the event. They allegedly launched violent assaults on police officers and Christian event goers for several hours, resulting in 23 arrests.
Instead of condemning the violent leftist agitators, Mayor Harrell issued a strong rebuke of Christians and blamed them for holding an event in the city's predominantly LGBTQ neighborhood. The mayor referred to the peaceful Christian group as "far right" and said he stood with the LGBTQ community. Harrell's office had suggested the group hold their concert in Cal Anderson Park rather than Pike Street, where the group initially sought a permit.
The faithful community was incensed by Mayor Harrell's remarks, prompting a group of Christian pastors to hold a Tuesday rally and call for the mayor's resignation. Mayor Harrell has since doubled down on his rebuke of Christians. Antifa militants and trans activists mobilized, again, to violently disrupt the event.
FBI Deputy Director Dan Bongino announced that the agency would be investigating targeted political violence against Christians, and the White House issued a statement condemning the leftwing violence. Additionally, Assistant Attorney General for the Justice Department's Civil Rights Division, Harmeet Dhillon, suggested that her department would also be investigating.
