Migrants are being detained by immigration agents in courthouse hallways nationwide, sometimes moments after pleading their cases, raising alarm among attorneys and advocates who say the practice is turning immigration courts from places of due process into zones of fear.

Families of immigrants arrested at the El Paso federal courthouse are left with uncertainty. Judge dismisses the cases and then the feds arrest them.

Immigration attorneys tell ABC News that federal agents are arresting migrants at immigration courts -- in some cases after their deportation cases have been dismissed.

Lawyers and relatives of the immigrants detained in a series of workplace raids in Los Angeles were rushing to locate them and intervene before removal.

The ICE agents detained the migrants after they checked in at an office on Elk St. right across from City Hall.

A group of ICE agents and the migrants they're holding in Djibouti following an order by a U.S. federal judge are at grave risk, an immigration official says.
