A leader of a Satanist group and three others were arrested Friday after a fight broke out inside the Kansas Statehouse after the leader allegedly tried to hold a Black Mass in the rotunda.

Michael Stewart, head of the Kansas City-area Satanic Grotto, was arrested after video showed him punching a counter-protester who tried to take his script.

Kansas Highway Patrol officers tackled and handcuffed him as he yelled, “Hail, Satan!” He was later released on $1,000 bond for disorderly conduct and unlawful assembly.

“There are more constructive ways to protest and express disagreements without insulting or denigrating sacred religious symbols,” Kelly said in an announcement about the event.

Pastor Jeremiah Hicks of The Cure Church in Kansas City, Kansas, warned against allowing the event. 

“The Bible says Satan comes to steal, kill and destroy, so when we dedicate a state to Satan, we’re dedicating it to death,” he declared.

Satanic Grotto followers argued the event was about free speech. Stewart’s wife, Maenad Bee, told reporters, “He’s only exercising his First Amendment rights.”

Two other followers of Stewart, Jocelyn Frazee, 32, and Sean Anderson, 50, were also arrested for unlawful assembly. Frazee had no bond set, and Anderson’s bond information was unavailable at the time of publication.

Marcus Schroeder, 21, a Christian counter-protester who tried to take Stewart’s script, was also arrested for disorderly conduct. His bond was set at $1,000.

Karla Delgado, who attended with her three young children, admitted she tried to stop Stewart’s Satanic ceremony.

“When we saw nobody stopping him, we tried to do it,” she said. In the chaos, her 4-year-old daughter was knocked down.

Stewart said his group scheduled the event thinking lawmakers would be in session. He hinted they may return.

“Maybe ‘un-baptisms,’ right here in the Capitol,” he said.

The Satanic Grotto did not immediately respond to Fox News Digital’s request for comment.
