Brady McCarron, spokesman for U.S. Marshals Service in Washington, D.C., confirmed Dugan was arrested at about 8 a.m. at the Milwaukee County Courthouse and is in federal custody.

Milwaukee County Circuit Judge Hannah Dugan was charged April 25 with two felonies on allegations of trying to help an undocumented immigrant avoid arrest after he appeared in her courtroom.

According to a 13-page complaint, Dugan, 65, is accused of obstructing a U.S. agency and concealing an individual to prevent an arrest. The two charges carry a maximum penalty of six years in prison and a $350,000 fine, but sentences in cases involving nonviolent offenses typically are much shorter.
