Rümeysa Öztürk was taken from street by masked, plainclothes officers in a Boston-area suburb on Tuesday

A Tufts University student who was detained by US immigration authorities this week, in an arrest that caused widespread outrage, cannot be deported without a court order, a US judge ordered on Friday.

Rümeysa Öztürk, 30, was detained by masked, plainclothes officers as she walked in a Boston-area suburb on Tuesday, an incident that was captured on surveillance footage that has since gone viral. Öztürk, who is being threatened with deportation to Turkey, is a Fulbright scholar and doctoral student in the US with a visa.
