A man appearing for his immigration hearing at 26 Federal Plaza in New York City was surrounded and detained by about a dozen officers while two women and a small boy were present. A crying woman clinging to him was wrenched away by a federal officer as he was taken into custody, and the judge closed the courtroom, preventing verification of further details. The Department of Homeland Security did not comment on the man's current status but said it offers parents the choice of being removed with their children or having them placed with a designated adult.
