People have noted that the Sergeant At Arms can make arrests, but I’m not finding that info anywhere.

"A proceeding was held at the bar of the House, and on January 4, 1796, the House, by a vote of 78-17, adopted a resolution finding Mr. Randall guilty of “a contempt to, and a breach of the privileges of, this House by attempting to corrupt the integrity of its Members in the manner laid to his charge.”33 The House ordered Mr. Randall to be brought to the bar, reprimanded by the Speaker, and held in custody until further resolution of the House.34 Mr. Randall was detained until January 13, 1796, when he was discharged by House resolution. Mr. Whitney, on the other hand, was absolved of any wrongdoing as the House determined that his actions were against a “member-elect,” and had taken place “away from the seat of government.”35"
