Read the document. The agents showed up to arrest Flores-Ruiz. The agents complied with the courtroom deputy to wait until after the proceeding and the deputy agreed to help with the arrest. They waited outside the courtroom at the deputy's request since it was a public space and they didnt have a warrent to enter the jury chamber. The judge was alerted of the officers and approached them and told them to leave. She directed them to go meet with another judge about the matter. She personally lead Flores-Ruiz out through the jury room.

All this stuff appears to be corroborated by witnesses.
