This week, in immigration court in Dallas, as well as in immigration courts across the country, some immigrants who attended their scheduled hearings were arrested by U.S. Immigration and Customs Enforcement Agents.

An attorney told KERA she saw at least three men detained after they had been told their deportation cases were dismissed. "When they step out in the hallway, that's where ICE is waiting for them.”

Federal agents arrest migrants inside courthouses, raising due process concerns among attorneys and advocates.
