The mystery surrounding Tufts University student Rumeysa Ozturk's whereabouts after she was picked up by federal immigration agents has shocked many — and is now complicating her legal proceedings. Why it matters: The case's question about jurisdiction — typically a granular area of court proceedings — could affect how ICE detains foreign-born residents and how it communicates about detentions in the future.

Within an hour of sweeping Tufts University student Rümeysa Öztürk off a sidewalk near the Somerville campus last week, immigration agents were quickly on the move.

BOSTON (AP) — Lawyers for a Tufts University doctoral student from Turkey who was seized by immigration officials off a street near Boston argued in federal court Thursday that she should be returned to Massachusetts, while the U.S. government insisted it did nothing wrong in moving her to a detention center in Louisiana.

Rümeysa Öztürk, the Turkish student detained by immigration officers in Boston last month, was moved across multiple state lines as part of a “highly unusual” and “secretive” attempt to keep her from accessing her attorney or being near her home,

Rumeysa Ozturk's detention sparked continued protests, allegations that federal officials broke the law, and more.

A Tufts graduate student from Turkey was moved from Massachusetts to Vermont and then Louisiana after being arrested according prosecutors who are challenging a federal judge's authority to review her detention.
