Judge Hannah Dugan will have a preliminary hearing in May. Her case would likely eventually go before a grand jury.

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.

The disruption has left people like LaTasha Tharp, whose case was being heard by Judge Dugan, concerned about delays and fairness in their legal proceedings.
