Lawyers for the US government on Thursday argued in court in Boston that they had transferred a doctoral student at nearby Tufts University to immigration detention in Louisiana before a court had ordered that she should not be removed from Massachusetts without prior notice.

At a hearing on Thursday morning in federal court, a lawyer for the student, a Turkish national, withdrew an emergency motion filed the previous day requesting that the government produce her after she was shipped off to Louisiana. The motion and one from the government were sealed.

Rumeysa Ozturk, 30, was sent to detention in the south on Wednesday after being snatched off the street outside her home on Tuesday.
