A Milwaukee judge arrested Friday for allegedly hiding a previously deported illegal immigrant in her jury room had a notice posted to her courtroom door for people who feel “unsafe” coming to the courthouse, Fox News learned Monday.

The notice posted to Milwaukee County Circuit Court Judge Hannah Dugan’s courtroom door was dated April 14, four days before she allegedly helped Eduardo Flores-Ruiz, an illegal immigrant, and his attorney leave the courthouse to evade ICE agents, Fox News observed.

The notice states: “ATTENTION – IF ANY ATTORNEY, WITNESS COORDINATOR, OR OTHER COURT OFFICIAL KNOWS OR BELIEVES THAT A PERSON FEELS UNSAFE COMING TO THE COURTHOUSE TO COURTROOM 615, PLEASE NOTIFY THE BRANCH 31 CLERK TO REQUEST COURT APPEARANCE VIA ZOOM.”

Dugan was arrested and charged with obstruction of an official proceeding after evidence came to light that she had shielded Flores-Ruiz from ICE agents, according to a criminal complaint. She was also charged with concealing an individual to prevent discovery and arrest.

Federal agents from ICE, FBI, CBP and DEA attempted to arrest Flores-Ruiz, an undocumented Mexican national, following his scheduled criminal court appearance before Dugan on April 18 to face three misdemeanor battery charges for allegedly beating two people.

Dugan demanded that the officers proceed to the chief judge’s office and – after his hearing ended – escorted Flores-Ruiz and his attorney out a restricted jury door, bypassing the public area where agents were waiting, in order to help him avoid arrest, per the complaint. 

Dugan was taken into custody by the FBI on Friday morning on the courthouse grounds, according to U.S. Marshals Service spokesperson Brady McCarron. She appeared briefly in federal court in Milwaukee later Friday before being released from custody. 

Dugan is not overseeing any cases and a reserve judge is taking over her cases while her own case plays out.
