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, a Turkish PhD student at Tufts University, was arrested by plainclothes federal agents on a Somerville sidewalk last week.
